Circuits

What is an open circuit?

• A closed loop where current flows continuously.

• A broken loop where current cannot flow.

• A circuit that is connected to a power source.

• A circuit that has multiple pathways for current.

What safety equipment should an electrician wear?

• Rubber gloves and other protective gear

• Safety goggles and a hard hat

• Steel-toed boots and a reflective vest

• Ear protection and a face shield

What is a closed circuit?

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

• A complete electrical loop that allows current to flow.

• A circuit that only works with batteries.

• A type of circuit that can only be used in series.

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

• A light bulb converts electrical energy into light energy when current flows through it.

• A light bulb stores electrical energy for later use.

• A light bulb regulates the flow of current in a circuit.

• A light bulb acts as a fuse to protect the circuit.

What is an insulator?

• A material that allows electricity to flow easily.

• A material that does not allow electricity to flow through it easily.

• A type of conductor that enhances electrical flow.

• A device used to measure electrical resistance.

What is the effect of adding more light bulbs in a series circuit?

• It increases the brightness of each bulb.

• It has no effect on the brightness of the bulbs.

• It decreases the brightness of each bulb because the total voltage is divided among them.

• It causes the bulbs to flicker.

What is the effect of adding more light bulbs in a parallel circuit?

• It increases the overall brightness of the circuit.

• It keeps the brightness of each bulb the same, as each bulb has its own path to the power source.

• It decreases the brightness of the bulbs due to increased resistance.

• It causes the bulbs to flicker due to uneven power distribution.

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 appliance used in homes.

• A circuit is a method of measuring electrical resistance.

What is a series circuit?

• A circuit where components are connected in a single path, allowing the same current to flow through all of them.

• A circuit that has multiple paths for current to flow, allowing for different components to operate independently.

• A circuit that only allows current to flow in one direction, preventing any reverse flow.

• A circuit that uses alternating current to power multiple devices simultaneously.

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.
