Best ResponseYou've already chosen the best response.0The RMS value of current is given by \[\frac{270}{666.76}amps\] The peak value is obtained by multiplying the RMS value by \[\sqrt{2}\]

Best ResponseYou've already chosen the best response.0(a) Is the correct answer (b) The current stated in the answer is the RMS (root mean square) value, and is not the peak value.

Best ResponseYou've already chosen the best response.0@jatasia It is not stated in the questions whether or not the line voltage is the RMS or the peak value. By convention if the value of an AC voltage is stated it is regarded as an RMS value unless stated otherwise.
