The peak voltage of the ac source is equal to :
(1) $\sqrt2$ times the rms value of the ac source
(2) 1/$\sqrt2$ times the rms value of the ac source
(3) the value of voltage supplied to the circuit
(4) the rms value of the ac source
(1) $\sqrt2$ times the rms value of the ac source
(2) 1/$\sqrt2$ times the rms value of the ac source
(3) the value of voltage supplied to the circuit
(4) the rms value of the ac source
