When an A.C. source is connected to an inductive circuit, the current lags behind the voltage. In an inductive circuit, the voltage leads the current because of the property of inductance.
The inductor resists changes in current, which causes the current to lag behind the voltage. The current reaches its peak value after the voltage reaches its peak. Therefore, the voltage is ahead of the current in phase.
Thus, the correct option is B.
In the A.C. circuit given below, voltmeters $ V_1 $ and $ V_2 $ read 100 V each. Find the reading of the voltmeter $ V_3 $ and the ammeter A.
An alternating voltage is given by \( e = 8 \sin(628.4 t) \).
Find:
(i) Peak value of e.m.f.
(ii) Frequency of e.m.f.
(iii) Instantaneous value of e.m.f. at time \( t = 10 \, {ms} \)
If the ratio of lengths, radii and Young's Moduli of steel and brass wires in the figure are $ a $, $ b $, and $ c $ respectively, then the corresponding ratio of increase in their lengths would be:
