A coil of reactance `8 Omega` and resistance `6 Omega` is connected in DC circuit then the effective resistance of the circuit …..`Omega`.

A

14

B

8

C

6

D

`24/7`

Text Solution

Verified by Experts

The correct Answer is:
C
Here magnitude of inductive reactance
`=X_L=omega_L=0`
`implies` For DC, effective resistance of given circuit,
`sqrt(R^2+X_L^2)=sqrtR^2(becauseX_L=0)`
=R
