An electric heater of resistance 50Ω is connected to an AC generator whose output voltage varies sinusoidally with a peak value of 311V.
(i) Calculate the rms value of the generator voltage.
(ii) Determine the rms current through the heater.
(iii) Find the average power dissipated in the heater.
(iv) Compute the electrical energy converted into heat by the heater in 10min of continuous operation.
