The alternating voltage is given by V=V_0\sin \left(\omega t+\dfrac{\pi}{6}\right). When will the voltage be maximum for the first time?<br>\{\sin(90)^{}^{\circ}=1\}

Options

  1. AT12\dfrac{T}{12}
  2. BT6\dfrac{T}{6}
  3. CT3\dfrac{T}{3}
  4. DT2\dfrac{T}{2}

Correct answer

B. T6\dfrac{T}{6}

Step-by-step solution

The given alternating voltage is V = V_0 \sin \left(\omega t + \dfrac{\pi}{6}\right).<br><br>For the voltage to be maximum, the value of the sine function must be 1.

\sin\left(\omega t + \dfrac{\pi}{6}\right) =1

The first maximum occurs when the phase angle is π2\dfrac{\pi}{2}.
