For maximum power from battery the internal resistance of battery r is

__________ are the terminals of a battery.

What is a battery ?

Assertion : Potential difference across the terminals of a battery is always less than the emf of the battery. Reason : During discharging of a battery potential differnce across to terminals of a battery is V = E -ir therefore V lt E

Statement I: Internal resistance of a battery is drawn parallel to a battery in electical circuit. Statement II: Heat generated in a battery is due to internal resistance.

A : The voltage across a battery may be less, equal or more than the emf of the battery. R : Voltage across a battery also depends on the magnitude and direction of current .
