E v =100 √2 V , E 0=?, E m =? E0=√2 Ev=√2(100 √2)=200 V E m =(2 E 0/π)=(2 × 200/3.14) =127.4 V

Q. In an a.c circuit, the rms voltage is $1002 V$ . Find the peak value of voltage and its mean value during a positive half cycle.

$200 V, 127.4 V$

$100 V, 127.4 V$

$120 V, 150 V$

$200 V, 150 V$

$E_{v} = 1002 V, E_{0} = ?, E_{m} = ?$
$E_{0} = 2 E_{v} = 2 (1002) = 200 V$
$E_{m} = \frac{2 E _{0}}{π} = \frac{2 \times 200}{3.14}$
$= 127.4 V$
