$A$ Watt-hour meter measures:

The power dissipated by a uniform wire of resistance $100 \Omega$ when a potential difference of $120 \text{ V}$ is applied across its ends is (in $W$)

When three identical bulbs of $60\, W$,$200\, V$ rating are connected in series to a $200\, V$ supply,the power drawn by them will be ................ $W$.

Define kilowatt hour and power.

The maximum current that flows through a fuse wire before it blows out varies with its radius as

How many electrons per second flow through a filament of a $120 \ V$,$60 \ W$ electric bulb?
