Question

A hot wire ammeter reads 20 A in AC. circuit. The peak value of the current is ______

पर्याय

• `20sqrt2`A

• `20/sqrt2`A

• 5π A

• `20/pi`A

Answer 1

A hot wire ammeter reads 20 A in AC. circuit. The peak value of the current is `underline(20sqrt2"A")`.

Explanation:

`"I"_"peak" = "I"_0 = "I"_"r.m.s" xx sqrt2 = 20sqrt2`A
