The alternating voltage is given by V=V₀ ( t+ 6 ) . When will the voltage be maximum for the first time? (90)^ =1

Options

  1. AT 12
  2. BT 6
  3. CT 3
  4. DT 2

Correct answer

B. T 6

Step-by-step solution

The given alternating voltage is V = V₀ ( t + 6 ) . For the voltage to be maximum, the value of the sine function must be 1 . ( t + 6 ) = 1 The first maximum occurs when the phase angle is 2 . t + 6 = 2 t = 2 - 6 = 3 Substituting = 2 T : 2 T t = 3 t = T 6 Answer: T 6
