Electricity Basics: Circuit

What is a circuit?

• A circuit is a type of bird

• A circuit is a type of dessert

• A circuit is a type of vehicle

• A circuit is a closed loop through which an electric current can flow.

Explain the difference between an open circuit and a closed circuit.

• An open circuit allows electricity to flow freely, while a closed circuit restricts the flow of electricity.

• An open circuit is always safe to touch, but a closed circuit can be dangerous.

• An open circuit is used for high-power devices, whereas a closed circuit is used for low-power devices.

• An open circuit has a gap that prevents electricity from flowing, whereas a closed circuit has a complete path for electricity to flow.

What is the role of a switch in a circuit?

• The switch reduces the resistance in the circuit

• The switch amplifies the current in the circuit

• The switch generates electricity in the circuit

• The role of a switch in a circuit is to control the flow of electricity by opening or closing the circuit.

Define the term 'conductor' in relation to circuits.

• A conductor is a material that absorbs electric current.

• A conductor in relation to circuits is a material that allows the flow of electric current.

• A conductor is a material that blocks the flow of electric current.

• A conductor is a material that generates electric current.

What is the purpose of a resistor in a circuit?

• The purpose of a resistor in a circuit is to limit current flow and voltage levels.

• The purpose of a resistor in a circuit is to store electrical energy

• The purpose of a resistor in a circuit is to amplify voltage levels

• The purpose of a resistor in a circuit is to increase current flow

Describe the function of a battery in a circuit.

• It changes the direction of electricity.

• It amplifies the flow of electricity.

Explain the concept of voltage in a circuit.

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

• Voltage is the brightness of the light bulbs in a circuit.

• Voltage is the resistance in a circuit.

• Voltage is the flow of electrons in a circuit.

What is the function of a fuse in a circuit?

• The function of a fuse in a circuit is to increase the current flow

• The function of a fuse in a circuit is to regulate the voltage

• The function of a fuse in a circuit is to store electrical energy

• The function of a fuse in a circuit is to protect the circuit from overcurrent by breaking the circuit when the current exceeds a certain threshold.

How does a series circuit differ from a parallel circuit?

• A series circuit has components connected wirelessly, while a parallel circuit has components connected through wires.

• A series circuit has components connected in a single path, while a parallel circuit has components connected in multiple paths.

• A series circuit has components connected in a random order, while a parallel circuit has components connected in a specific order.

• A series circuit has components connected in multiple paths, while a parallel circuit has components connected in a single path.
