According to Joule law of heating Heat produced in a conductor,

H = I^{2} Rt

where,

I

= Current flowing through the conductor

R

= Resistance of the. conductor

t

= Time. for which current flows through the conductor.

∴ H \propto I^{2}

Q. Which of the following is a correct statement?

Heat produced in a conductor varies directly as the current flowing.

Heat produced in a conductor varies inversely as the current flowing.

Heat produced in a conductor varies directly as the square of the current flowing.

Heat produced in a conductor varies inversely as the square of the current flowing.

According to Joule law of heating Heat produced in a conductor, H=I2Rt where, I = Current flowing through the conductor R = Resistance of the. conductor t = Time. for which current flows through the conductor. ∴H∝I2

According to Joule law of heating Heat produced in a conductor,
$H = I^{2} Rt$
where,
$I$ = Current flowing through the conductor
$R$ = Resistance of the. conductor
$t$ = Time. for which current flows through the conductor.
$∴ H \propto I^{2}$
