• Electrons

• Protons

• Neutrons

• Photons

Those materials that let the current flow through them are called...

• conductors

• insulators

• generator

• controllers

They supply energy to the circuit such us batteries, dynamos and cells.

• Generators

• Controllers

• Receivers

• Conductors

The function of a switch is...

• to supply energy to the circuit.

• to transform electric energy into light.

• to open or close the circuit so the current can flow.

• to protect the circuit.

They transforms the electrical energy into another typo of energy like motion, light, sound and heat.

• Generators

• Controllers

• Receivers
