In an a. c. circuit the instantaneous current and e.m.f. are represented as i=i_o ( t- 6 ) and E=E_o ( t+ 3 ) respectively. The voltage leads the current by

Options

  1. A2
  2. B4
  3. C3
  4. D6

Correct answer

A. 2

Step-by-step solution

The phase of the current =- 6 The phase of voltage =+ 3 Hence the voltage leads current by phase angle = ( 6 )- (- 3 )= 2
