The delay in the protection of koalas is "bad news," said Dai, president of the Koala Action Association. "Over the years, we've worked tirelessly to collect data on the number of koalas," Debbie said. "That data should be enough to make a decision".

The postponement of the decision on koala protection "is really bad news," Debbie noted, chairman of the koala's action team. "We have worked tirelessly for years to collect demographic data," the finger said. "This data is enough to make a decision. ”

The delay in the decision to protect koalas "is really bad news," Debbie said, noting the Koala Action Team. "We work tirelessly for many YERS to collect data on the population," the finger said. "This data is enough to make a decision. ”

It's really bad news that the decision to protect koalas didn't pass," said Debbie Pointing, captain of the koala action team, "We've been working hard for several years to collect data on koala populations," Pointing continued, adding, "and that's enough data to make a decision to protect koalas." ”

Figure: Energy storage device and resistive load connected to external terminal (a) storage device represented by a constant voltage power supply and a fixed lumped resistance with a value of rint (b) a closed circuit formed by an external load.

In this case, the closed circuit can be analyzed simply by Ohm's law, and the current formula can be calculated by the following formula.

The actual voltage passing through the load can be calculated using the following formula.

Formula: This formula can be rewritten.

As can be seen from the equation, the available voltage released at the end of the load decreases as the internal resistance of the power supply increases. Therefore, a good power supply requires not only a higher open circuit voltage, but also a very low internal resistance. We can use the following formula to calculate the energy released by the load.

FormulaFrom the above formula, it can be seen that the total energy that can be transmitted to the load in this ideal state with the internal resistance of the power supply is 0 is V2 RL, and the actual maximum energy that can be transmitted is limited by the internal resistance of the power supply. For example, the internal resistance of a rechargeable battery increases with consumption. Even batteries that can provide a constant open circuit voltage will continue to decline as the internal resistance increases.
