Understanding Electric Circuits

What is a battery in an electric circuit?

• A battery is a component that regulates voltage in a circuit.

• A battery is a type of resistor in a circuit.

• A battery is a device that only consumes electrical energy.

• A battery is a device that stores and provides electrical energy in a circuit.

Name three components of an electric circuit.

• Resistor, capacitor, transformer

• Generator, insulator, relay

• Battery, switch, diode

• Power source, conductors, load

What is the purpose of a switch in a circuit?

• To convert AC to DC in a circuit.

• To control the flow of electricity in a circuit.

• To store electrical energy for later use.

• To increase the voltage in a circuit.

What are the two main types of electric circuits?

• Open and Closed Circuits

• Direct and Alternating Circuits

• High and Low Voltage Circuits

Define an open circuit.

• An open circuit is a type of battery that stores energy.

• An open circuit is a complete electrical circuit with no resistance.

• An open circuit is an incomplete electrical circuit where current cannot flow.

• An open circuit allows current to flow freely.

Define a closed circuit.

• A closed circuit is an electrical circuit that is complete and allows current to flow.

• A closed circuit is an electrical circuit that is open and prevents current flow.

• A closed circuit is a type of circuit that only works with batteries.

• A closed circuit is a circuit that has multiple paths for current to flow.

What happens when a circuit is open?

• The circuit generates power.

• Current flows freely through the circuit.

• The circuit becomes a short circuit.

• No current flows through the circuit.

What happens when a circuit is closed?

• The circuit generates heat without current.

• The circuit becomes open.

• The circuit emits light without current.

• Electric current flows through the circuit.
