Questions|Power Dissipated Across A Resistance|Examples

In given circuit determine . (a) The rate at which chemical energy of the cell is consumed (b) The rate at which heat is generated inside the battery (c ) Electric power output (d) Which resistance consumes maximum power (e ) Power dissipated across 4Omega resistance

STATEMENT-1: AC source is connected across a circuit. Power dissipated in circuit is P . The power is dissipated only across resistance. STATEMENT-2: Inductor and capacitor will not consume any power in AC circuit.

Power dissipated in pure inductance will be-

Calculate the power dissipated in the various resistances and the power given by the cells in the circuit shown in Fig: 6.14.

A charged capacitor is discharged through a resistance. The time constant of the circuit is eta . Then the value of time constant for the power dissipated through the resistance will be
