Answer to Question #83643 in Electric Circuits for Darsh

Question #83643
if the temperature of a battery connected conducting resistance wire reduces by cooling process then how current in it will change?
Expert's answer

Batteries have internal resistance. This resistance is different from resistance of wires. Resistance of metal wires decreases when they are cooling. The internal resistance of a battery increases with cooling because this resistance is a result of ions’ motion. The lower the temperature – the slower their speed – the lower the conductivity – the higher the resistance.
