MHT CET · Physics · Alternating Current
The resistance offered by the inductor \(\left(X_L\right)\) in an ac circuit is
- A inversely proportional to inductance and directly proportional to the frequency of alternating current
- B inversely proportional to inductance and frequency of the alternating current
- C directly proportional to inductance and frequency of alternating current
- D inversely proportional to frequency of alternating current and directly proportional to inductance.
Answer & Solution
Correct Answer
(C) directly proportional to inductance and frequency of alternating current
Step-by-step Solution
Detailed explanation
The expression for inductive reactance is:
\(
X_{\mathrm{L}}=2 \pi f L
\)
Therefore, \(X_{\mathrm{L}} \propto L\) and \(X_{\mathrm{L}} \propto f\).
\(
X_{\mathrm{L}}=2 \pi f L
\)
Therefore, \(X_{\mathrm{L}} \propto L\) and \(X_{\mathrm{L}} \propto f\).
