WebFor this example, we will assume that a 0 to 2 Vdc input will be used to measure 4 to 20 mA. Ohms law states: R=V/I where V is the Voltage, I is the current and R is the resistance. R=2V/0.020A = 100Ω. When 20 mA flows through a 100Ω resistor, it will drop 2 volts. When 4 mA flows through a 100Ω resistor, it will drop 0.4 volts. WebIn electricity, the measurement of work performed, or the unit of power (P) is called the Watt. Without digressing too much, Ohm's Law states: P = V x I or P = I² x R That is, Power equals Voltage times Current, or Power equals Current squared times Resistance. This formula is what our calculators use to compute Wattage values for you. shanghai people\u0027s publishing house https://boxh.net
