What is the frequency of the alternating current

Reference no: EM13561120

A light bulb is connected to a 240 Vwall socket. The current in the bulb depends on the time taccording to the relation I = (2.121 A) sin[ (439.6Hz) t ].

a) What is the frequency of the alternating current?
b) What is the resistance of the bulb's filament?
c) What is the average power delivered to the light bulb?
