The r.m.s value of a supply voltage is quoted at 200v. What is the approximate peak value of the voltage?
200volts
300volts
283volts
250volts
Correct answer is C
Vr.m.s = V0 ÷ V2, where Vr.m.s rep. to as voltage root –square mean, v = peak voltage
Vr.m.s = 200volt, v = ?
200 = V0 ÷ V2
V0 = 200v2
= 200 × 1.414
= 282.8 volts V0 = b &approx.; 283 volts
