What is the peak value of 220 V ac ?

Text Solution

Verified by Experts

`E_v= 220 V`
`E_0 = ?`
` E_0 = sqrt2 E_v`
`= 1.414 xx 220`
`E_0 = 311.08 A `

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : An alternating voltage of 220V is more dangerous than a d.c. supply of 220 V. Reason : The peak value of 220V a.c. is about 311 V.
