Dr. Sunil Kushwaha Solutions for Chapter: Electricity, Exercise 9: Summative Assessment

Electric current represents:

The resistance of a straight conductor does not depend on its:

The electrical resistance of metals:

The power rating of an electrical appliance is given by:

An electric bulb is rated at $220 \mathrm{V}, 100 \mathrm{W}$, then its resistance will be:

$\mathit{3}\mathit{.}\mathit{6}\mathit{\times }{\mathit{10}}^{\mathit{6}} \mathrm{J}$ is equal to:

Two bulbs of rating $100 \mathrm{W} - 220 \mathrm{V}$ and $200 \mathrm{W} - 220 \mathrm{V}$ are connected in series to a supply of $220 \mathrm{V}$ then:

What determines the rate at which energy is delivered by a current:
