In the given LCR series circuit find the reading (in A) of the hot wire ammeter. (there all hot wire meters are ideal)

Text Solution

Verified by Experts

The correct Answer is:
4
`V_(C)-V_(L)=120`
`V_(R)^(2)+(V_(C)-V_(L))^(2)=E_(v)^(2)`
`V_(R)^(2)+(120)^(2)=(200)^(2) implies V_(R)=160`
`I=(V_R)/(R) =(160)/(40)=4A`.
