What is the amount of power delivered by the ac source in the circuit shown (in watts)

A

500 watt

B

1014 watt

C

1514 watt

D

2013 watt

Text Solution

Verified by Experts

The correct Answer is:
C

`I_(1_("rms")) =(E_("rms"))/(sqrt(X_(C)^(2)+R_(1)^(2)))=(130)/(13) =10A`
`i_(2_("rms")) =(E_("rms"))/(sqrt(X_(L)^(2)+R_(2)^(2)))=13 A`
Power dissipated
`=i_(1_("rms"))^(2)R_(1)+R_(2_("rms"))^(2)R_(2)=10^(2)xx5+13^(2)xx6`
=Power delivered by battery
`= 500 + 169 xx 6 = 1514` watt.
