Physics - Current Electricity Question with Solution | TestHub

Thermal energy or heat developed is given by,

$\mathrm{H}={\mathrm{i}}^2\mathrm{R}\mathrm{t}$

In series combination, the current flowing through all the elements is the same, so

$\frac{{\mathrm{H}}_1}{{\mathrm{H}}_2}=\frac{{\mathrm{R}}_1}{{\mathrm{R}}_2}$

$\frac{{\mathrm{H}}_1}{{\mathrm{H}}_2}=\frac{\mathrm{R}}{2\mathrm{R}}$

$\frac{{\mathrm{H}}_1}{{\mathrm{H}}_2}=\frac{1}{2}$
