Electricity and Circuits

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the path for electricity to flow, preventing current from moving through the circuit.

Front

What is the unit of measurement for electric current?

Back

Electric current is measured in Amperes (A), commonly referred to as 'amps'.

What happens when a switch in a circuit is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and enabling devices like buzzers to operate.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for current to flow, and each component is connected across the same voltage source.

Front

What are electrons?

Back

Electrons are negatively charged subatomic particles that flow through conductors, such as wires, to create electric current.

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electric current to flow from a power source, through components, and back to the power source.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push electrons through the circuit, creating current.

Front

What is a buzzer in an electrical circuit?

Back

A buzzer is an electromechanical device that produces sound when electric current passes through it.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so current flows through each component in turn. In a parallel circuit, components are connected across the same voltage source, allowing current to flow through multiple paths.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, typically measured in Ohms (Ω).
