Heat produced at constant potential difference =(V2/R) So, H propto (1/R)

Q. Heat produced in a wire of resistance R due to current flowing at constant potential difference, is proportional to :

$\frac{1}{R ^{2}}$

$\frac{1}{R}$

$R$

$R^{2}$

Heat produced at constant potential difference $= \frac{V ^{2}}{R}$ So, $H \propto \frac{1}{R}$

Q. Heat produced in a wire of resistance R due to current flowing at constant potential difference, is proportional to :

R21​

R1​

R

R2

Heat produced at constant potential difference =RV2​ So, H∝R1​

$\frac{1}{R ^{2}}$

$\frac{1}{R}$

$R$

$R^{2}$

Heat produced at constant potential difference $= \frac{V ^{2}}{R}$ So, $H \propto \frac{1}{R}$
