As shown in figure value of inductive reactance `X_(L)` will be (source voltage is 100 volt)

A

`40 Omega`

B

`30 Omega`

C

`50 Omega`

D

Can have any value

Text Solution

Verified by Experts

The correct Answer is:
C
`V = I sqrt((20 + 10)^(2) (X_(L) + X_(L) - X_(C_(2)))^(2))`
`100 = 2 sqrt((30)^(2) + (30 + X_(L) - 40)^(2))`
`(50)^(2) = (30)^(2) + (X_(L) - 10)^(2)`
`(X_(L) - 10^(2)) - 80 xx 20 , X_(L) - 10 = 40 , X_(L) = 50 Omega`
