The circuit below shows an AC power supply connected to a resistor R-2220 AN M R The current through the resistor is measured by an ideal Ac ammeter thes sero resistance), and the potential difference across the resistor s matured by an ideal voltmeter (has infinite resistance). If the maximum voltage supplied by the power supply is a 140 determine the following (a) reading on the ammeter (in A) (b) reading on the voltmeter (in V) V
