Question

In the given circuit the reading of voltmeter $$V_1$$ and $$V_2$$ are 300 volts each. The reading of the voltmeter $$V_3$$ and ammeter A are respectively

A
100 V, 2.0 A
B
150 V, 2.2 A
C
220 V, 2.2 A
D
220 V, 2.0 A

Solution

The correct option is C 220 V, 2.2 A$${ V }_{ 1 }$$ and $${ V }_{ 2 }$$ are equal and out of phase with each other and thus get cancelled. Thus $${ V }_{ 3 }=220V$$ and $$i = \dfrac { 220 }{ 100 } =2.2A$$Physics
