Electric Resistance Converter
Electric resistance is how strongly a component opposes current flow. The SI unit is the ohm, defined by Ohm's law as one volt per ampere. Resistors are specified from milliohms in power circuits up to megohms and gigaohms in high-impedance measurement.
13 units supported Base unit ohm (Ω)
