Priyanka B Solutions for Chapter: Electricity, Exercise 4: Assignment-2

Mention the factor that maintains the flow of charge through a conductor.
(List: Resistance, Voltmeter, Ammeter, Current, Potential difference)

If $12 \mathrm{J}$ of work is done in moving $2 \mathrm{C}$ of electric charge through a conductor, what is the potential difference at the ends of the conductor?

What is the potential of Earth?

By drawing a diagram, show the movement of electrons when a positively charged body is connected to Earth.

Define potential difference.

When can we say that the potential difference between two points is $5 \mathrm{V}?$

Define the term 'volt'.

State the relationship between work, charge and potential difference for an electric circuit. Calculate the potential difference between two terminals of a battery, if $100 \mathrm{joules}$ of work is required to transfer $20 \mathrm{coulombs}$ of charge from one terminal of battery to the other.
