Question

The maximum current supplied by a generator to a 25 omh circuit is 6.2 a what is the rms potential difference

Answer 1

The rms potential difference is "110V".


This is how we calculate this;

I x R /√2

Now potting the values, I = 6.2 and R = 25, we get

6.2 x 25 /√2
= 155/ √2 
=109.6 V = 110V
