Question:easy

The alternating voltage is given by \(V=V_{0}\sin \left(\omega t+\frac{\pi }{6}\right)\). When will the voltage be maximum for the first time?
\(\{\sin (90)^{\circ }=1\}\)

Show Hint

The voltage is maximum when the phase first reaches a quarter of a cycle. Subtract the initial phase and convert the remaining phase to time.

  • \(\frac{T}{12}\)
  • \(\frac{T}{6}\)
  • \(\frac{T}{3}\)
  • \(\frac{T}{2}\)
Show Solution

The Correct Option is B

Solution and Explanation

Step 1: Phase fraction
The extra phase needed is $\dfrac{\pi}{3}$, which is $\dfrac{1}{6}$ of a full cycle $2\pi$.

Step 2: Result
So the time is one-sixth of the period, $\dfrac{T}{6}$.

Step 3: Final answer
One-sixth of a cycle is needed, so $t=\frac{T}{6}$.

Final Answer:
One-sixth of a cycle is needed, so $t=\frac{T}{6}$. \[ \boxed{\text{(B) }\dfrac{T}{6}} \]
