Question

The root mean square value of potential difference of
an alternating current in a circuit is 100v2(100root2) volt. Find
out peak value of potential difference and average
value of potential difference over a full cycle.​

Answer 1

The voltage across the circuit is  127.32 volts

Explanation:

Given data:

Alternating current = 100 v^2(100 root^2) volt.

Formula for calculating peak value of potential difference;

• V peak = √2 x V(r.m.s)
• V peak = √2 x 100 √2
• V peak = 200 Volts

Similarly, Formula for calculating average value of potential difference.

• V average = 2/ pi x V peak
• V average = 2/ pi x 200
• V average = 127.32 volts

Hence the voltage across the circuit is  127.32 volts
