Question
An electric bulb and a capacitor are connected in series with an AC source. On increasing the frequency of the source, the brightness of the bulb :
Options
A.increase
B.decreases
C.remains unchanged
D.sometimes increases and sometimes decreases
Solution
XC = 
will decrease if we increase frequency then z will decrease so current will increase & intensity will increase.
