Electric Circuits Quiz

What is an electric circuit?

• A device that converts electrical energy into mechanical energy.

• A type of battery used to store electrical energy.

• A material that does not allow electric current to flow through it.

• A closed loop or pathway that allows electric current to flow through it.

Define electric current.

• The flow of sound in a conductor.

• The flow of heat in a conductor.

• The flow of water in a conductor.

• The flow of electric charge in a conductor.

What is the purpose of a voltmeter in an electric circuit?

• To measure voltage or potential difference

• To measure current flow

• To measure resistance

• To measure power consumption

What is the purpose of an ammeter in an electric circuit?

• To measure electric current

• To measure electric resistance

• To measure electric voltage

• To measure electric power

What are resistors in an electric circuit?

• Resistors are used to store electric charge in a circuit.

• Resistors are passive electronic components that limit the flow of electric current in a circuit.

• Resistors are active electronic components that amplify the flow of electric current in a circuit.

• Resistors have no effect on the flow of electric current in a circuit.

What is a series circuit?

• A series circuit is a circuit in which the components are connected in a random order, so the current flows through each component unpredictably.

• A series circuit is a circuit in which the components are connected in a single loop, so the current flows through each component in sequence.

• A series circuit is a circuit in which the components are not connected to each other, so the current does not flow.

• A series circuit is a circuit in which the components are connected in parallel, so the current flows through each component simultaneously.

What is a parallel circuit?

• An electrical circuit that has only one path for the current to flow.

• An electrical circuit that has no path for the current to flow.

• An electrical circuit that has multiple paths for the current to flow.

• An electrical circuit that has multiple sources of current.

How is voltage distributed in a series circuit?

• Equally

• Unequally

• Inversely

• Randomly

How is voltage distributed in a parallel circuit?

• Voltage is distributed evenly across all branches

• Voltage is concentrated in one branch only

• Voltage is distributed across each branch or resistor

• Voltage is not distributed in a parallel circuit

How is resistance calculated in a series circuit?

• By multiplying the individual resistances.

• By adding up the individual resistances.

• By subtracting the individual resistances.

• By dividing the individual resistances.
