Can the charger still work if it flashes a spark?

It is normal for the plug to be inserted into the socket to have an electric spark flash, mainly because the charger itself is a loop energized state, and the moment it is plugged into the socket, it is working, and the general electric spark time is short, and the current intensity is relatively small, which will not damage the charger, nor will it damage the original price inside the charger. If the charger's internal components are damaged, it will not work, rather than the voltage will increase for a long time.

When the plug of the iPhone charger is plugged into an outlet, there will be a spark. Can a spark damage the transformer inside the charger? When the plug is plugged into the socket for a long time, it is normal for the charger's voltage and current to flicker.

The main reason is that the charger itself is loop-energized and works when the plug is plugged into an outlet. In general, the spark time is short, the current intensity is relatively small, and it will not damage the charger and the inside of the original charger**. If the internal parts of the charger are damaged, it will not work instead of the voltage rising for a long time.

Academic science is a concept as opposed to applied science, which is related to Merton's strict distinction between science and technology. Academic science, which first appeared in France and Germany in the first half of the 19th century, refers to scientific research carried out in universities, is associated with higher education, and can be found in a large number of collegiate settings. Merton believed that the science of the academy was governed by the "Merton Criterion" and the "spirit of science".

First, from the point of view of the scientific researchers of the academy, they are "all those who agree with some universal principle of reason and objectivity, who have a high degree of professional skill and trust, and who are able to work together in trust in the pursuit of truth and the good of mankind"[1]37; Second, "from a sociological point of view, academic science as a whole is an institution. In essence, he is a social order that relies heavily on the established relationship between personal trust and institutional trust"[1]39, and there is no unified institutional organization in academic science that controls them, and they are not formally systematized. Collegiate science is best seen as a culture rather than an organized institution, benefiting from private funding.

In the middle of the 20th century, with the changes in the world political situation after World War II, the emergence of economic crises, and the advent of the era of big science (big science has the characteristics of large-scale, high-investment, complex organization, and integration of science and technology), the mode of production of science has gradually changed, and academic science is giving way to post-academic science. Science has become a highly differentiated and highly integrated complex system, and scientists are distributed in highly professional positions in this system, engaged in knowledge production that is difficult for laymen to understand. Here, scientists are paid salaries and engaged in highly specialized work, so it is difficult for the former amateurs to gain a foothold, and science has become a highly institutionalized industry and a means of livelihood for scientists.

Post-academic science is the result of numerous timely solutions to pressing practical problems; It is the product of expediency, not the result of design. Yet it has built a more or less coherent culture, not because it was planned to be so, but because science is a typically complex self-organizing social system that opportunistically adapts to changing circumstances. [1] 83 Ziman argues that post-academic science is not, as many scientists still expect, only briefly deviate from the trajectory of science as we know it.

It is not just a new mode of knowledge production, "it is a completely new way of life", it is the result of countless instant solutions to immediate practical problems.

Did your charger flash a spark while charging? In this case, it is likely to be connected, in this case, you can only take your charger and charge it to see if it can be used normally?

The reason for the burnout and breakdown of the internal components of the charger is that the breakdown causes a short circuit in the circuit, and the socket position will flash a spark, and the part of the short circuit has been broken down, so it can no longer be used.

The method of dimensioning the material by using the corrosion phenomenon generated by spark discharge is called EDM. Die-sinking EDM is the discharge of a spark in a liquid medium in the lower voltage range. EDM is mainly done by machine shops.

EDM is a self-excited discharge, which is characterized by the following:

The two electrodes of a spark discharge have a high voltage before discharge, and when the two electrodes are close to each other, the medium is broken down in the meantime, and then the spark discharge occurs. As the breakdown process occurs, the resistance between the two electrodes decreases dramatically, and the voltage between the electrodes decreases dramatically. The spark channel must be extinguished in time after a short period of time (usually 10-7-10-3s).

to keep the spark discharged"Cold pole"The characteristic (i.e., the heat energy converted by the channel energy does not have time to reach the depth of the electrode) allows the channel energy to act on a very small range. The effect of channel energy can cause local corrosion of the electrode.

It works.

It is normal for the plug to be inserted into the socket to produce a spark, the greater the power of the plug-in, the more obvious the electrical appliance, which will not cause the current to be unstable, only the high-power electrical appliances will produce a certain voltage drop after being connected, and the small drop in current caused by the general electrical appliances has no impact, some electronic appliances such as TVs and computers have voltage stabilization circuits at the power supply. EDM isn't a big deal.

If you are afraid of crackling discharge, you can plug in the charger with the power out of the socket and turn on the power switch, so that the discharge will occur in the enclosed space of the power switch and will not disturb you.

Precautions for the use of the charging head.

Before charging for the first time, read the charger instruction manual carefully, operate according to the instructions, and whether the power supply of the charger is consistent with the local mains voltage. If the charger has two voltages to choose from, you should carefully look at where the conversion button on the charger is, and the voltage should be consistent with the local voltage.

When using the charger to charge the battery, plug in the output plug of the charger first, and then the input plug. When charging, the power indicator of the charger shows red, and the charging indicator also shows red; When fully charged, the charging indicator is green. When stopping charging, unplug the input plug of the charger first, and then unplug the output plug of the charger.
