MCQ
An alternating voltage is represented as $E = 20\,sin \,300t.$ The average value of voltage over one cycle will be.......$V$
  • $0$
  • B
    $10$
  • C
    $20\sqrt 2 $ 
  • D
    $\frac{{20}}{{\sqrt 2 }}$ 

Answer

Correct option: A.
$0$
a
(a) answer is zero

$E=20 \sin 300 t$

Average value of any $AC$ voltage over a cycle $= 0$ an it will have equal values for both positive and negative cycle, which will cancel out each other and resultant is zero
