The Resistance

Resistance opposes current flow. It is like electrical (friction) This resistance slows the flow of current. Every electrical component or circuit has resistance.
The standard unit of resistance is the (ohm). This is sometimes abbreviated by theupper-case Greek letter omega.we’ll just write it out as “ohm” or “ohms.” You’ll sometimes hear about kilo ohms where 1 kilo ohm = 1,000 ohms, or aboutmega ohms, where 1 mega ohm = 1,000 kilo ohms = 1,000,000 ohms. And, this resistance changes electrical energy into another form of energy like heat, light, motion. A special meter, called an ohmmeter, can measure the resistance of a device in ohms when no current is flowing.
