Can a battery 12V9A be plugged into two 70W bulbs?

Yes, yes, but the brightness is reduced, and it will also have an effect on the bulb.

If the bulb is 12 volts. It can be plugged in parallel. If the bulb is 220 volts, it will not light up when plugged in.

Depending on how long you plan to use it, you can choose a battery based on how long you want to use it.

The battery is a device that directly converts chemical energy into electrical energy, and is a battery designed according to rechargeability, which is recharged through reversible chemical reaction, usually referring to lead-acid battery, which is one of the batteries and belongs to secondary batteries.

Its working principle: when charging, the external electrical energy is used to regenerate the internal active substance, the electrical energy is stored as chemical energy, and the chemical energy is converted into electrical energy output again when it needs to be discharged, such as mobile phone batteries commonly used in life.

The relationship between the internal resistance of the battery and the rated capacity, and the relationship between the internal resistance of the same type of battery and the SOC of the charge. More than 10 years ago, people tried to use the change of internal resistance (or conductance) of VRLA batteries to test the capacity and life of the battery, but failed.

People have put forward higher and higher requirements for the high-current discharge capacity of power batteries, which requires that the internal resistance of the battery be reduced as much as possible. Therefore, this paper will further explore and clarify the internal relationship between the internal resistance and capacity of some commonly used batteries.

This depends on how long it is planned to use, according to the use time to choose the battery, the choice of 12V is 90 watts for 1 hour, plus the loss of other lines and the battery itself, it is good to make a valuation of 100 watts per hour. If you need to use it for 20 hours, choose a 100*20 battery that is, 12 volts 2 ampere, the larger the battery, the longer the belt, and the lighting is recommended to be about 12 volts 5 ampere.

Storage battery is a general term for all chemical batteries that can be recharged and reused after a certain amount of power.

Also known as a rechargeable battery, it can be charged because its chemical action can be reversed after being connected to an external power source. There are many different types of chemicals used to make batteries, and their designs are also different; As a result, their voltage, capacity, size, and weight are also different.

To use more than 45A, less than 45A takes less than 5 hours, I use a 12V 45A battery, [2 30W energy-saving lamps and 1 18W fluorescent lamp can only be used for 7 hours] [12V 45A battery 250 yuan, plus a silicon rectifier 6V 12V 20A charger about 50].

When choosing a battery, you need to know your intended use time. 12V90W lamp, discharge current I=90 12=, how many AH batteries are you using, that number is divided, is the maximum use time (hours), for example, using a 75AH battery, the maximum use time is 75 hours; With a 30AH battery, the maximum use time is 30 hours. When choosing, it is best to leave a certain margin to avoid damage to the battery due to complete photoelectric discharge.

90W current, 24Ah battery can be used for up to 3 hours, how long to light up to how big you are.

The maximum storage capacity of the sufficient 24ah battery is theoretically 288W, and the power factor is calculated according to 70%, and it can be lit continuously for two hours after being fully charged.

Friend, you can buy a 100-amp or so one that is enough for you to use. It's easy to lose power if it's small.

Rated current of 6V10W bulb: I=10 6=

So the 12V10Ah battery connected to the 6V10W bulb can be used: T=10Ah hours.

A 12-volt car battery with a 100-watt bulb can be used for 7 hours; With 7 x 100 watt bulbs can be used for 1 hour.

According to the information you provided, the 12V battery has a capacity of 7AH, which is used to light a 12V 100W bulb, let's calculate how long it can be used.

First of all, we need to convert the bulb power from watts to amps, and the formula can be used for muffle: power (watts) = voltage (volts) current (amps).

According to the formula, a 100-watt bulb at 12 volts requires a current: 100 watts of 12 volts amps.

Next, we can use the formula to change the capacity of the battery from ampere-hour to hour, using the formula: capacity (hours) = capacity (ampere-hour) load current (amps).

According to the formula, dividing the battery capacity at 7 amps by the load current at amps, we can get: 7 amps per hour.

So, using a 12v battery 7ah to light a 12v 100 watt bulb can be used for about an hour.

How long it lasts depends on the amount of current. If the current is 140 mA, then the power is 12 140 = 1680 watts =, here the bulb power is 140 watts =, and the time it can be used = hours.

One battery is 12V20A, and 6 batteries are how many amps.

Dear, hello, I'm glad to serve you: an electric 12V20A, 6 batteries are how many amps: I'm glad to answer for you, if it is connected in series, it is still 20A, but the voltage is 72V.

If the parallel current is 120A, the voltage is still 12V. Extended information: The role of the battery is to supply electricity to the engine, when the vehicle is ready to start, the battery will be discharged to provide power to the starter, and the starter will drive the flywheel and crankshaft to rotate, so as to start the vehicle.

When the engine is underpowered or not started, it provides power to the electrical appliances in the car, such as the audio system and lighting system, and when the engine starts to supply power normally, the battery excitter beam will collect and store the electrical energy for use. It uses a lead plate filled with spongy lead celery as the negative electrode, a lead plate filled with Mingyun lead dioxide as the positive electrode, and 22 28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy.

Summary. The two batteries are connected in parallel: the positive pole (+) of battery A is connected to the positive pole (+) of battery B, and then the negative pole (-) of battery A is connected to the negative pole (-) of battery B to 12V.

One battery is 12V20A, and 6 batteries are how many amps.

Hello dear, happy to answer for you. One battery is 12V20A, how many amps are 6 batteries, and if the 6 batteries are connected in series, it is still 20A, but the voltage is 72V. If the hand is defeated and connected to the bucket bend, the current is 120A, and the voltage is still 12V.

How do you explain series and parallel?

Hello dear, series connection is to connect your 6 batteries together. A single battery is then used as a positive and negative interface for connection.

How is parallel connection done?

The two batteries are connected in parallel: the high pole (+) of the old dust pool of electric A is connected to the positive pole (+) of battery B, and then the negative pole (-) of battery A is connected to the negative pole (-) of electric Qiqi pool of electric B to 12V.

Six batteries are connected in series at 20 amps, why is it 120 amps in parallel?

Hello dear, the parallel battery is the total power of 6 batteries used at the same time. Then the 6 batteries will also be installed.

Do I need to buy a range extender, is it 72 volt 20 amp or 120 amp?

Hello dear, choose 72 volts 29 amps.

Why is the road table sometimes visible and sometimes not?

Hello dear, 1Most of the reason is that the speed sensor is damaged. 2.The transmission connection cable may be broken. 3.It is more likely that there is a question about Jian You. 4.The clips at the junction of the roadcode and gearbox are loose.
