Question

A potencial difference of 250 volts is applied across a resistance of 500 ohm in an electric iron. calculate current heat energy produce in joule in 10 sec.

please friends help me
i will mark it as brainlist

Answer 1

v=250 volts
R=500 ohm

we need to find current :-

according to ohm"s law:-
I=V/R
I=250/500
I=0.5 ampere

heat energy=I²Rt
  h=0.5²×500×10
H=1250 JOULE
