What is an insulator
A material which allows electrons to collect on the surface but doesn’t allow them to pass along it
What is a Conductor
A material which allows electrons to move along it and can lose electrons to other materials
Why are resistors used
Makes it harder for electrons to flow to reduce current
What is a fuse
A piece of wire inside an electrical circuit to handle a certain amount of current
What is current
The flow of electrons in a circuit
How do you calculate voltage?
Calculate the voltage using Voltage = Current × Resistance
