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.

When the voltage increases, the flow of charges

The symbol of voltage is

• E is the symbol used for electric field.

Voltmeter is connected in ____ to measure the voltage of any circuit.

• It is connected in parallel so that it does not draw any current itself (due to its high resistance) and does not affect the net resistance of the circuit.

Which of the compounds shows the highest lattice energy?

They are non-conductors of electricity in solid, molten or aqueous state.

Which of the following is NOT TRUE about covalent compounds?

They are conductors of electricity in solid, molten or aqueous state.

They have higher enthalpies of fusion and vaporization than molecular compounds.
