A sinusoidal waveform, when observed on an oscilloscope, has a peak to peak amplitude of 6 cm. If the vertical sensitivity setting is 5V/ cm, then rms value of the voltage will be ____________V

1. 10
2. 12.4
3. 10.6
4. 11.6

Correct Option: C

Amplitude of the signal

=	6 × 5	= 15 V
	2

∴ rms value =	15	= 10.6 V
	√2
