The voltage of an $AC$ source varies with time according to the equation,$V = 100 \sin(100 \pi t) \cos(100 \pi t)$. Where $t$ is in seconds and $V$ is in volts. Then:

  • A
    The peak voltage of the source is $100 \text{ V}$.
  • B
    The peak voltage of the source is $(100 / \sqrt{2}) \text{ V}$.
  • C
    The peak voltage of the source is $50 \text{ V}$.
  • D
    The frequency of the source is $50 \text{ Hz}$.
