In the circuit shown in fig. `X_(C ) = 100 Omega,(X_L)=200 Omega and R=100 Omega`. The effective current through the source is

A

`2 A`

B

`2 sqrt(A)`

C

`0.5 A`

D

`sqrt(0.4) A`

Text Solution

Verified by Experts

The correct Answer is:
B
`I_(R ) = (V)/(R ) = (200)/(100) = 2A`
`I' = (V)/(X_(L) - X_(C )) = (200)/(100) = 2A`
`I = sqrt(I_(R )^(2) + I'^(2)) = 2 sqrt(2) A`
