Practice for Electricity and Circuit Test

Front

What is a series circuit?

Back

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

Front

What happens to the flow of electricity in a series circuit if one component fails?

Back

The flow of electricity stops completely.

Front

What is a circuit diagram?

Back

A circuit diagram is a shorthand way of drawing electrical circuits, showing the components and their connections.

Front

What material stops the flow of electricity?

Back

Insulators are materials that stop the flow of electricity.

Front

In the formula I = Q/t, what does Q represent?

Back

Q represents electric charge.

Front

What is the role of a conductor in an electrical circuit?

Back

A conductor allows the flow of electric current through it.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts.

Front

What is current?

Back

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

Front

What is resistance?

Back

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

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R): V = I × R.
