JEE Mains · Physics · STD 12 -7. Alternating current
The effective current \(I\) in the given circuit at very high frequencies will be \(.......A\)
- A \(4\)
- B \(44\)
- C \(42\)
- D \(46\)
Answer & Solution
Correct Answer
(B) \(44\)
Step-by-step Solution
Detailed explanation
At very high frequencies, \(X _{ C }=\frac{1}{\omega C } \approx 0\) Also \(X _{ L }=\omega L \approx \infty\) Thus, equivalent circuit can be redrawn as \(Z =1+2+2=5 \Omega\) \(I =\frac{220 V }{5 \Omega}=44 A\)
