Statement I: An electric lamp connected in series with a variable capacitor and AC source, its brightness increases with increase in capacitance.
Statement II: Capacitive reactance decreases with increase in capacitance of capacitor.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct.
Capacitive reactance 
, when capacitance C increases, the capacitive reactance decreases. Due to decreases in its value, the current in the circuit will increases 
and hence brightness of source (or electric lamp) will also increases.
