In `L-C-R` series `AC` circuit,

A

If `R` is increased, then current will decrease

B

If `L` is increased, then current will decrease

C

If `C` is increased, then current will increase

D

If `C` is increased, then current will decrease

Text Solution

Verified by Experts

The correct Answer is:
A
`I=V/Z`
`=V/sqrt(R^2+(omegaL~1/(omegaC))^(2))`
By increasing `R` current will definitely decrease by change in `L` or `C`, current may increase or decrease.
