Alternating Current | MCQs
-
A. Both (A) & (B) are true
-
B. Pure inductive circuit
-
C. Pure capacitive circuit
-
D. RLC series AC circuit at resonance
Explanation
- In a pure capacitive circuit, the current leads the voltage by 90°.
- In a pure inductive circuit, the current lags behind the voltage by 90°.
- In both cases, there is a 90° phase difference between current and voltage
-
A. 1 A²
-
B. √2 A
-
C. 2.5A
-
D. 5A
Explanation
- Peak value (I₀) = √2 A
- RMS value (I_RMS) = I₀ / √2 = 1 A
- Mean square value = (I_RMS)² = 1 A²
So, the mean square value is 1 A² — not one of the options given earlier.
Final answer: 1 A²
