Alternating Current vs Direct Current

Q1:

What is the rms voltage value of an ac signal whose peak oscilloscope display uses 3 major divisions above the zero setting? (V/cm = 5)

A 5.3 V

B 10.6 V

C 15.0 V

D 21.2 V

ANS:B - 10.6 V

5V/cm for 3 divisions we have 5 * 3 = 15v Vrms = 0.707 * Vp.
Vrms = 0.707*15,
Vrms = 10.6.
