Question

Q1
The correct expression for heat generated (H) in a coil of resistance R, connected to voltage V and drawing current I in time t
O H=12R
O HE VIL
O H=v2t/R
O All of the above​

Answer 1

C) H= V²t/R

Heat generated = Work done

= power * time

= I²R * t

= (V/R)²R * t          (Since I=V/R)          

= V²t/R

Answer 2

$H=I^2RT$correct expression for heat generated (H) in a coil of resistance R, Connected to voltage V and drawing current I in time t,

$=IR*IT$

Work done is converted into heat energy

$H=I^2RT$

$H=(V^2)t/R$

$H=I^2*R$
