What is the difference between series and parallel circuits?

• Parallel circuits have only one component, while series circuits have multiple components.

• In series circuits, components are connected in multiple paths, while in parallel circuits, components are connected in a single path.

• In series circuits, components are connected in a single path, while in parallel circuits, components are connected in multiple paths.

• Series circuits have higher voltage than parallel circuits.

Explain the concept of voltage in electricity.

• Voltage is the flow of electrons in a circuit.

• Voltage is the brightness of a light bulb.

• Voltage in electricity is the difference in electric potential energy between two points in an electric circuit.

• Voltage is the resistance in an electric circuit.

What is the role of an insulator in electrical wiring?

• Enhance the flow of electricity

• Generate heat in the wiring

• Regulate the voltage

How does a capacitor store electrical energy?

• By generating sound waves when charged

• By emitting light when charged

• By accumulating and holding opposite charges on its two plates

• By converting electrical energy into heat

Describe the process of grounding in electrical systems.

• Grounding involves connecting electrical circuits to the sky to prevent electric shock.

• Grounding in electrical systems is the process of connecting electrical circuits to the earth or a large conducting body to prevent electric shock, protect equipment, and ensure proper functioning of the system.

• Grounding in electrical systems is the act of increasing the voltage in circuits.

• Grounding is the process of removing all electrical connections from a system.
