Exercise

Flow of negatively charged electrons is called _____.
(Choose from the following- electric current/ static charge)

$100$ resistors of $R \mathrm{\Omega }$ each are connected in series with a battery of $12 \mathrm{V}$ in the circuit. The potential difference across each resistor will be _____ $\mathrm{V}$.

The electric power of heater is $0.5 \mathrm{kW}$. It is used for $20 \min$, then generated heat will be

Consider the circuit given. Calculate the total current in the circuit.

The equivalent resistance of two resistors of $4 \mathrm{\Omega }$ each connected in parallel is $8 \mathrm{\Omega }$.

To secure maximum equivalent resistance using hundred resistors, all the resistors should be connected in parallel.

A volt is a unit of

Based on which of the following effects of current does an electric fuse work?
