The working principle of a resistor is simple. The resistor has two conductive terminals connected to a resistor element, and this element will resist electric current. The resistance of a resistor is determined by its physical dimensions, material properties, and number of turns in the resistor element. The higher the resistance, the more the electric current is limited. The power rating of the resistor will determine the maximum power that the resistor can dissipate, so higher ratings will need larger resistors. The tolerance rating of a resistor will determine the accuracy of the resistance.
