The instantaneous voltage of a 50 ~Hz generator giving peak voltage as 300 ~V , The generator equation for this voltage is

Options

  1. AV=50 300 i
  2. BV=300 100 t
  3. CV=6 100 t
  4. DV=50 100 t

Correct answer

B. V=300 100 t

Step-by-step solution

Given, frequency of AC , v =50 ~Hz Peak voltage, V₀=300 ~V Generator equation for the voltage is given as aligned & V=V₀ t =& V₀ 2 v t =& 300 (2 50 t) =& 300 100 t aligned
