Voltage and current in an AC circuit are given by V=5 (100 t- 6 ) and I=4 (100 t+ 6 )

Options

  1. Avoltage leads the current by 30^
  2. Bcurrent leads the voltage by 30^
  3. Ccurrent leads the voltage by 60^
  4. Dvoltage leads the current by 60^

Correct answer

C. current leads the voltage by 60^

Step-by-step solution

Net phase difference between current and voltage = 6 - (- 6 )= 3 =60^ Hence, current leads the voltage by 60^ .
