Lakhmir Singh and Manjit Kaur Solutions for Chapter: Electricity, Exercise 11: Very Short Answer Type Questions

Keeping the resistance constant, the potential difference applied across the ends of a component is halved. By how much does the current change?

State the factors on which the strength of the electric current flowing in a given conductor depends.

Which has less electrical resistance: a thin wire or a thick wire (of the same length and same material)?

Keeping the potential difference constant, the resistance of a circuit is halved. By how much does the current change?

A potential difference of $20 \mathrm{volts}$ is applied across the ends of a resistance of $5 \mathrm{ohms}$. What current will flow in the resistance?

A resistance of $20 \mathrm{ohms}$ has a current of $2 \mathrm{amperes}$ flowing in it. What potential difference is there between its ends?

A current of $5 \mathrm{amperes}$ flows through a wire whose ends are at a potential difference of $3 \mathrm{volts}$. Calculate the resistance of the wire.

Ohm's law states a relation between potential difference and _____ (Electric power/ Electric current/ Electric energy).
