A resistor is an electronic component used to resist the flow of electrical current. Resistors are passive components that introduce resistance within the flow of an electrical circuit. A resistor that performs in accordance to Ohm’s law is called an Ohmic resistor. When current is passed through an Ohmic resistor, the voltage drop across the terminals is proportional to the magnitude of resistance. We are able to manipulate these resistances by utilising different materials such as MANGANIN® or ISAOHM® with varying properties such as wire thickness, length or form, all of these factors are able to resist an electrical flow at different rates.
