Flow is...

• The pathway through which electrical current flows

• Material that allows electric current to flow through easily

• The flow of electricity around a circuit

• To move or travel smoothly in a certain direction

A path through which an electrical current can travel is called -

• energy

• a conductor

• a closed circuit

• an insulator
