Electricity Vocabulary

The flow of electrons between atoms is called:

• Electric current

• Magnetic field

• Thermal conduction

• Nuclear fusion

Answer explanation

The flow of electrons between atoms is known as electric current. It is the movement of charged particles, which is essential for the functioning of electrical devices and circuits.

What are tiny negatively charged particles that jump from atom to atom?

• Protons

• Neutrons

• Electrons

• Photons

What word comes from the 15th century meaning 'Go Around'?

• Circuit

• Navigate

• Revolve

• Encircle

Answer explanation

The word 'Circuit' originates from the 15th century and means 'Go Around'. It refers to a path that goes around a particular area, making it the correct choice compared to the other options.

What opens and closes a circuit?

• A switch

• A resistor

• A capacitor

• A diode

Answer explanation

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity. Unlike resistors, capacitors, or diodes, which serve different functions, a switch directly controls the circuit's connectivity.

A complete loop where electrical current will flow is called a:

• Circuit

• Conductor

• Insulator

• Resistor

What does not create a complete loop, therefore electrical current will not flow?

• Open circuit

• Closed circuit

• Short circuit

• Parallel circuit

Answer explanation

An open circuit does not create a complete loop, preventing electrical current from flowing. In contrast, closed circuits allow current to flow, while short and parallel circuits involve different configurations that do not apply here.

A compact energy source is called:

• Battery

• Generator

• Solar Panel

• Wind Turbine

Answer explanation

A battery is a compact energy source that stores electrical energy for later use, making it the correct choice. Generators, solar panels, and wind turbines are larger systems that convert energy from other sources.

Materials that allow electricity to flow are called:

• Insulators

• Conductors

• Resistors

• Capacitors

Answer explanation

Materials that allow electricity to flow easily are called conductors. Insulators resist electrical flow, resistors limit current, and capacitors store electrical energy. Therefore, the correct answer is conductors.

Materials that prevent electricity from flowing are called:

• Conductors

• Insulators

• Semiconductors

• Superconductors

Answer explanation

Materials that prevent electricity from flowing are called insulators. Unlike conductors, which allow electricity to pass through, insulators resist electrical flow, making them essential for safety in electrical applications.

What allows some electricity to flow, but not all of it?

• Conductor

• Insulator

• Resistor

• Superconductor
