Resistors, Capacitors, and Inductors
Electric circuits are used to provide a path to electric current. They commonly use three basic electrical components, which are resistors, capacitors, and inductors. They affect the electric current and changes the behavior of the circuit. Resistor A resistor is an electrical component, which has a certain amount of resistance. […]
