A bulb and capacitor are connected in series to a source of alternating current.What will happen on increasing the frequency of the AC
Asked by Debolina Banerjee | 27th Sep, 2010, 03:37: PM
If the frequency of a.c. source is increased gradually, the impedance decreases first, becomes minimum while at resonance and starts increasing afterwards. Thus the capacitative reactance changes with the frequency and hence also the current flowing through the circuit changes.
We hope that clarifies your query.
