How much potential difference is required to do 100 J of work to carry a charge of 20 C between two points?

Calculate the work done if a charge of 5 C moving across two points has a potential difference equal to 20 V.

Amount of work done by Sona in bringing a unit positive charge from one end to another end of a conductor is called ______.

A charge of 5 C flows through the copper wire for 2 s connected across a cell of potential difference 20 V, the work done is

A charge of 60 C is transferred from a cloud to the ground due to a potential difference of 8 MV, energy consumed during this is

Identify the potential difference across this home appliance.

The unit of voltage is Volt.

Identify the order of the items to be placed in the boxes.

The unit of voltage is

• Watt is the unit of power.
• Coulomb is the unit of charge.
• Joule is the unit of work.

Electric potential energy has

• It is defined as the amount of work done to bring a unit positive charge from infinity to a point in the electric field.
• And work only has magnitude and no direction.

Voltage can be defined as

One volt will drive _________ coulomb charge.

• If 1 joule of work is done in carrying 1 coulomb of charge, from infinity to a point in the electric field, then the potential at that point is 1 volt.

A voltmeter is given to you to measure the voltage. Which voltmeter will you choose?

Voltage is a form of

_______ is used to measure the potential difference between two points in any circuit.

• An ammeter is used to measure the current flowing in a circuit.
• An odometer is used for measuring the distance traveled by a vehicle.

The term voltage was introduced by an Italian physicist named

• Alessandro Volta also invented a chemical battery.
