Conductor Semiconductor Insulator

What are the charged particles in a conductor free to do?

• Reflect light

• Stay stationary within the atomic structure

• Absorb energy from the circuit

• Move around and flow as an electric current

What is the term used for materials where the charge carriers are locked into the atomic structure and not free to move?

• Thermistor

• Semiconductor

• Insulator

• Conductor
