RESISTOR Definition We define RESISTOR |
RESISTOR - A two-terminal electronic component that resists an electrical current and turns the extra current into heat. Resistors are rated in ohms, and can be used to regulate the voltage and current in a circuit. Basically, a resistor resists the flow of electricity. Resistors are used to lower voltages and currents so that components that require smaller voltage/current can function properly. If a power supply puts out 12 volts and you have a chip that runs on three, you need a resistor to cut down the voltage. |
