WebSo to display the units or multiples of units for either Resistance, Current or Voltage we would use as an example: 1kV = 1 kilo-volt – which is equal to 1,000 Volts.; 1mA = 1 milli-amp – which is equal to one thousandths (1/1000) of an Ampere.; 47kΩ = 47 kilo-ohms – which is equal to 47 thousand Ohms.; 1kW = 1 kilo-watt – which is equal to 1,000 Watts. WebElectrical. Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called "electrical charge") flowing past a point in a circuit over a given time.
