Circuits

What is the function of a light bulb in a circuit?

• A light bulb converts electrical energy into light energy.

• A light bulb stores electrical energy for later use.

• A light bulb increases the voltage in a circuit.

• A light bulb acts as a resistor to limit current.

What is an open circuit?

• A circuit that allows current to flow freely.

• A circuit that is not complete, preventing current from flowing.

• A circuit that has a short circuit condition.

• A circuit that is designed for high voltage applications.

Why do electricians wear rubber gloves?

• To protect themselves from electric shock.

• To keep their hands warm in cold weather.

• To improve their grip on tools.

• To prevent dirt from getting on their hands.

What happens if a light bulb burns out in a series circuit?

• The entire circuit continues to work normally.

• Only the burned-out bulb stops working.

• The entire circuit stops working.

• The other bulbs become brighter.

What is the difference between a series and a parallel circuit?

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

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

• In a series circuit, all components share the same voltage, while in a parallel circuit, each component has its own voltage.

• In a series circuit, components can be turned on and off independently, while in a parallel circuit, they cannot.

What happens if a light bulb burns out in a parallel circuit?

• All bulbs go out

• Only the burned-out bulb goes out

• The other bulbs continue to work

• The circuit is completely broken

What is a circuit?

• A circuit is a closed path through which electric current flows.

• A circuit is a device that stores electrical energy.

• A circuit is a type of electrical insulation.

• A circuit is a measure of electrical resistance.

What is the purpose of wires in a circuit?

• To connect different components in a circuit, allowing electricity to flow between them.

• To insulate the circuit from external interference.

• To store electrical energy for later use.

• To convert electrical energy into mechanical energy.

What is a closed circuit?

• A circuit that is open and does not allow current to flow.

• A circuit that allows current to flow continuously.

• A circuit that is incomplete and cannot function.

• A circuit that only works with batteries.

What is a conductor?

• A material that allows electricity to flow through it easily.

• A material that prevents electricity from flowing.

• A type of electrical device that stores energy.

• A material that only conducts heat, not electricity.
