Question

In the circuit shown below, what will be the readings of the voltmeter and ammeter

  1. 800 V, 2A    
  2. 300 V, 2A    
  3. 220 V, 2.2 A    
  4. 100 V, 2A    

The correct answer is: 220 V, 2.2 A


    V to the power of 2 end exponent equals V subscript R end subscript superscript 2 end superscript plus left parenthesis V subscript L end subscript minus V subscript C end subscript right parenthesis to the power of 2 end exponentÞ V subscript R end subscript equals V equals 220 V
    Also i equals fraction numerator 220 over denominator 100 end fraction equals 2.2 A
