Exploring Electric Current

It generates heat.

It causes the conductor to expand.

It increases resistance.

It produces light.

Magnetic fields are produced by the resistance of materials to electric flow.

Electric current creates a magnetic field through static charge.

Electric current generates a magnetic field only in superconductors.

Electric current produces a magnetic field due to the movement of charged particles.

Electromagnetic induction occurs only in superconductors.

A constant magnetic field creates an electric current in a conductor.

The principle behind electromagnetic induction is that a changing magnetic field induces an electromotive force (EMF) in a conductor.

A changing electric field induces a magnetic field in a conductor.

The compass needle spins rapidly in circles.

The compass needle remains stationary.

The compass needle points directly to the electric source.

The compass needle deflects from its normal position.

To convert AC to DC in the circuit.

To store electrical energy for later use.

The role of a fuse in an electrical circuit is to protect the circuit from overcurrent by breaking the circuit when the current exceeds a safe level.

To increase the voltage in the circuit.

Chemical reactions occur without any external energy.

Electric current can only produce heat.

Electric current causes chemical reactions through electrolysis.

Electric current is used solely for powering devices.
