MCQ
Electrical power can be written as $P =\frac{ QV }{t}$.
  • A
    VI
  • B
    $I^2 R$
  • C
    $\frac{ VQ }{ t }$
  • ✓
    All of these
✓

Answer

Correct option: D.
All of these
(d)
All of these
Explanation:
$P =\frac{\text { Energy supplied }( E )}{\text { Time }(t)}$
$P =\frac{ VIt }{t}= VI$
But $I =\frac{ Q }{t}$
$P =\frac{ QV }{t}$
