Basic Electrical Concepts and Components Quiz

Capacitor stores electrical charge.

Ohm is the unit of electrical resistance.

Coulomb is the SI unit of electric charge.

AC stands for Alternating Current in the context of electrical power.

The purpose of a ground wire is to provide a return path for fault currents in an electrical system.

Ohm's Law describes the relationship between current and resistance in a DC circuit.

A diode controls current flow in one direction in an electrical circuit.

The total resistance increases with the addition of resistors in a series circuit.

A fuse protects against overcurrent in an electrical circuit.

A short circuit refers to an unintended path of low resistance in electrical circuits.

A transformer's primary function is to step up or step down voltage.

The phenomenon of a material allowing the flow of electric current is called conduction.

Increasing the number of turns in an inductor increases its inductance.

The phenomenon of a material opposing the flow of electric current is called resistance.

Connecting capacitors in series decreases the total capacitance.
