Electrical circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow from a power source, through conductors, and back to the source.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber, glass, or plastic.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for current to flow.

Front

What is alternating current (AC)?

Back

Alternating current (AC) is an electric current that reverses direction periodically, commonly used in household outlets.

Front

What is direct current (DC)?

Back

Direct current (DC) is an electric current that flows in one direction only, commonly used in batteries.
