About these units
Resistance is how strongly a material opposes electric current. The SI unit is the ohm, one volt per ampere. Resistors are marked in ohms, kilohms (k) and megohms (M); cable and contact resistance is measured in milliohms, insulation in megohms or gigaohms.
Ohm's law links the three quantities: volts = amps × ohms.
