Electric power consumed by resistor | Electric power supplied and consumed by cell | KCL & KVL

Electric power consumed by resistor | Electric power supplied/consumed by cell| KCL and KVL | EMF and internal resistance of a cell

The power consumed by the 4 V battery is

Units Of Electric And Electric Power

Assertion:- Average power consumed in an accircuit is equal to average power consumed by resistors in the circuit. Reason:- Average power consumed by capacitor and inductor in zero.

In the circuit shown find (a)the power drawn from the cell, (b)the power consumed by the resistor which is converted into heat and ( c)the power given of the inductor.

Equivalent cells || KVL || KCL

Statement I: When an external resistor of resistance R (connected across a cell to internal resistance r ) is varied, power consumed by resistance R is maximum when R = r. Statement II: Power consumed by a resistor of constant resistance R is maximum when current through it is maximum.

In an AC circuit, the electrical energy is consumed in

Power consumed in an AC circuit becomes zero if
