What is the average power dissipated by a resistor of resistance r = 25 ω in an lrc circuit for which the power factor is equal to 0.25 and the maximum voltage of the ac source is 8 v?

0.08 w

Explanation:

AVERAGE POWER : Average power is defined as the average work per unit time. average power is denoted by P its depend on the voltage current and power factor.

the expression for the average power is given as

P= cosΦ

We have given maximum voltage =8 volt

=

power factor =.25

resistance =25Ω

power factor =

power factor=

From here Z=100

P= × ×cosΦ

=5.6577×0.05677×0.25

=0.08w

it doesn't. it was imagined up in the middle ages.
