What is static electricity?

• The transfer of negatively charged particles between materials

• The flow of energy as a current through the circuit

• The creation of a magnetic field by a current flowing through a wire

• The transformation of electrical energy into radiant energy

Answer explanation

Static electricity is the transfer of negatively charged particles between materials.

What is an example of an insulator?

• Gold

• Silver

• Copper

• Rubber

Answer explanation

An example of an insulator is rubber. Unlike gold, silver, and copper, rubber does not conduct electricity and is therefore a good insulator.

In a lamp, electrical energy is transformed into which form of energy?

• Radiant energy

• Mechanical energy

• Thermal energy

• Static energy

Answer explanation

In a lamp, electrical energy is transformed into radiant energy, which produces light.

What creates a magnetic field when flowing through a wire?

• Power

• Resistance

• Voltage

• Current

Answer explanation

When current flows through a wire, it creates a magnetic field. This is due to the movement of charged particles. The correct choice is 'Current'.

What does a closed circuit allow?

• Electricity to flow through insulators

• No electricity to flow

• Electricity to flow outside the circuit

• Electricity to flow within the circuit

Answer explanation

A closed circuit allows electricity to flow within the circuit.

What is an example of static electricity?

• Toaster

• Lightning

• Lamp

• Fan

Answer explanation

Static electricity is exemplified by lightning, which is a natural phenomenon that occurs during thunderstorms.

What is the main purpose of a circuit?

• To transform electrical energy into mechanical energy

• To create a magnetic field

• To generate static electricity

• To allow energy to move from one location to another

Answer explanation

The main purpose of a circuit is to allow energy to move from one location to another.
