Exploring Electric Current

Front

What is the magnetic effect of electric current?

Back

Electric current produces a magnetic field.

Front

How does a compass react to an electric current?

Back

A compass needle deflects due to the magnetic field generated by the electric current.

Front

What is the principle behind electromagnets?

Back

Electromagnets work by generating a magnetic field through electric current.

Front

Name one application of electric current in daily life.

Back

Powering household appliances like refrigerators

Front

How does electric current produce heat?

Back

Electric current produces heat through resistance in conductors, converting electrical energy into thermal energy.

Front

What is the role of electric current in electric motors?

Back

Electric current generates a magnetic field that produces torque to rotate the motor.

Front

Explain how electric current can create a magnetic field.

Back

Electric current creates a magnetic field due to the movement of charged particles in the conductor.

Front

What is the function of a solenoid?

Back

The function of a solenoid is to convert electrical energy into linear mechanical motion.

Front

How is electric current used in transformers?

Back

Electric current in transformers is used to create a magnetic field that induces voltage in another coil.

Front

What is the relationship between electric current and magnetism?

Back

Electric current creates a magnetic field, and a changing magnetic field can induce electric current.
