$A$ $5\;A$ fuse wire can withstand a maximum power of $1\;W$ in the circuit. The resistance of the fuse wire is

Which of the following graphs correctly represents the variation of heat energy $(U)$ produced in a metallic conductor in a given time as a function of potential difference $(V)$ across the conductor?

How much electric energy is consumed by an average Indian household in one second?

Water in an electric kettle starts boiling in $15 \ min$ after being switched on. If the length of the heating wire is reduced to $2/3$ of its original length,the time taken to boil the same amount of water will be ........... $min$.

Electric power is transmitted over long distances through conducting wires at high voltage because

The emf of a car battery is $12 \ V$. If the internal resistance of the battery is $0.4 \ \Omega$,then the maximum power drawn from the battery is . . . . . . $W$.
