Answer:

52.2232 V

Explanation:

We have given the capacitance of the capacitor C = 3.3 F

Power P = 75 W

The time for which the bulb is operated t = 1 minute = 60 sec

Energy [tex]E=power\times time =75\times 60=4500J[/tex]

The energy storied in the capacitor is given by [tex]E=\frac{1}{2}CV^2[/tex]

[tex]4500=\frac{1}{2}3.3V^2[/tex]

[tex]V^2=2727.2727[/tex]

[tex]V=52.2232V[/tex]
