Question

Desiring expression for electrical energy consumed in a device in does term of V,I and t where V is THE

Answer 1

Potential difference between terminals....

Answer 2

Explanation:

Energy =( V²/R²)t

We know that work done ,

W=QV

.•. P=W/t

now,

P=QV/t

V=IR

P=(Q/t)I²R

=I²R

Energy =P×t

=I²R×t

=(V²/R²)×R×t

=(V²/R)t

energy=(V²/R)t

where,V=voltage

R = resistance

t=time

hope this may help u plz mark me as branilist.....
