In a Ac circuit aV and I are given below , then find the power dissiapted in the circuit
V= 50 sin (50t) V
` I=50 sin (50+(pi/3))mA `

A

0.625W

B

1.25w

C

2.50w

D

5.0w

Text Solution

Verified by Experts

The correct Answer is:
B

A shunt resistance , `S=3Omega` is connected in parallel
`Rightarrow (R(S+X))/(sx)=(62.5)/(37.5)`
`2(3+x)/(3x)=(1.667)`1,
`(2(3+X))=5X`
`therefore x=2Omega`
