Question

"A high voltage battery must have a large internal resistance." Justify.

Hint:

High voltage batteries often have a larger internal resistance to regulate the current and enhance safety.

Answer 1

A high voltage battery typically has a large internal resistance to limit the current drawn from it and to avoid overloading. High voltage batteries are used to power devices that require a large voltage, but by having a large internal resistance, they ensure that the current remains within safe limits. This prevents excessive heat generation and potential damage to the battery or the connected devices.
