Ohm’s Law describes how voltage is proportional to current where the constant of proportionality is resistance

2
New cards

Define Ohmic Resistors

Ohmic resistors are materials which have a constant resistance regardless of the amount of current passing through them or the voltage applied across them

3
New cards

Define Non-Ohmic Resistors

Non-Ohmic resistors are materials which have a resistance that is dependant on the amount of current passing through them or the voltage applied across them

4
New cards

Define a conductor

A conductor is a substance that contains charged particles which are free to move throughout the substance

5
New cards

Define an insulator

An insulator is a substance that does not contain charged particles which are free to move
