Q1:

A heater is rated at 230 V, 5 A AC. Then

A both the current and voltage are peak values

B both the current and voltage are rms values

C the current is peak value and voltage is rms value

D the current is rms value and voltage is peak value

ANS:D - the current is rms value and voltage is peak value

In heaters, the ratings are specified in terms of rms values.
