The instantaneous values of current and voltage in an AC circuit are given by I=6 (100 t+ 4 ) and V=5 (100 t- 4 ) , then

Options

  1. Avoltage leads the current by 45^
  2. Bcurrent leads the voltage by 45^
  3. Cvoltage leads the current by 90^
  4. Dcurrent leads the voltage by 90^

Correct answer

D. current leads the voltage by 90^

Step-by-step solution

The phase difference between instantaneous value of I and V is = 4 - (- 4 )= 2 Hence, the current leads voltage by 90^
