Sorry, I couldn’t resist!
The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits, they can be found. The resistance is measured in ohms (Ω). An ohm is a resistance that occurs when one ampere (A) current passes through a resistor with a one-volt (V) drop across its terminals. The current is proportional to the voltage across the terminal ends. Ohm’s law represents this ratio:
Resistors are used for many purposes.
