Understanding Electric Circuits

What is an electric circuit?

• A type of electrical appliance that uses power.

• A device that stores electrical energy.

• A series of batteries connected in parallel.

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

What are the two main types of electric circuits?

• Static and Dynamic

• Open and Closed

• Direct and Alternating

• Series and Parallel

What is the role of a battery in a circuit?

• To store electrical energy for later use.

• The role of a battery in a circuit is to supply electrical energy.

• To convert electrical energy into mechanical energy.

• To regulate the flow of current in the circuit.

What is a conductor?

• A conductor is a material that facilitates the flow of electric current or heat.

• A conductor is a type of insulator that blocks electric current.

• A conductor is a device that stores electric energy.

• A conductor is a material that only conducts sound.

What is an insulator?

• A device that amplifies electrical signals.

• An insulator is a material that resists the flow of electric current or heat.

• A conductor that enhances electric flow.

• A type of material that generates heat.

What does a switch do in a circuit?

• A switch converts AC to DC in a circuit.

• A switch stores electrical energy for later use.

• A switch amplifies the electrical signal in a circuit.

• A switch controls the flow of electricity in a circuit by opening or closing it.

What is the difference between series and parallel circuits?

• Series circuits have a single path for current, while parallel circuits have multiple paths.

• Series circuits are always more efficient than parallel circuits.

• Parallel circuits have a single path for current.

• Series circuits can have multiple paths for current.

What happens if one component fails in a series circuit?

• If one component fails in a series circuit, the entire circuit stops functioning.

• The circuit reroutes power to bypass the failed component.

• Only the failed component needs to be replaced for the circuit to work again.

• The circuit continues to function with reduced power.

What happens if one component fails in a parallel circuit?

• The circuit becomes a series circuit.

• The entire circuit stops working.

• The other components continue to function normally.

• All components are damaged.

What is voltage?

• Voltage is the power consumed by an electrical device measured in watts.

• Voltage is the flow of electric current measured in amperes.

• Voltage is the electric potential difference measured in volts.

• Voltage is the resistance to electric flow measured in ohms.
