Electric Charge and Current

Front

What is electric charge?

Back

Electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field. It can be positive or negative.

Front

What is the unit of electric charge?

Back

The unit of electric charge is the coulomb (C).

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically measured in amperes (A).

Front

What is a conductor?

Back

A conductor is a material that allows electric charge to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric charge, preventing electricity from passing through, such as rubber or glass.

Front

What happens when two like charges are brought together?

Back

Two like charges repel each other.

Front

What happens when two opposite charges are brought together?

Back

Two opposite charges attract each other.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause sparks or shocks.

Front

What is the role of a circuit in electric current?

Back

A circuit provides a complete path for electric current to flow, allowing devices to operate.

Front

What is the function of a battery in a circuit?

Back

A battery provides a source of electric energy, creating a potential difference that drives the current through the circuit.
