Electricity Practice

Front

What is a load in an electrical circuit?

Back

A load is a component that consumes electrical energy, such as a lightbulb.

Front

What is static electricity?

Back

Static electricity is the build-up of electric charge on an object's surface.

Front

What happens in a series circuit if one component fails?

Back

If one component fails in a series circuit, all components will stop working.

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 current flows through each component in turn.

Front

How does adding more bulbs in a parallel circuit affect their brightness?

Back

Adding more bulbs in a parallel circuit does not change the brightness of each bulb; it stays the same.

Front

What is a parallel circuit?

Back

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

Front

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

Back

A conductor is a material that allows the flow of electric current, such as copper wire.

Front

What is the function of a switch in an electrical circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is the difference between voltage and current?

Back

Voltage is the electrical potential difference that drives current through a circuit, while current is the flow of electric charge.

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). It is expressed as V = I × R.
