Power, Voltage and Current shows the relationship between the voltage (V), current (I) and power (W). Power, Voltage and Current formula is: W = I * V Where: V: Voltage, in Volts (V) I: Current, in Amps (A) W: Power, in J...
电力口诀(Power formula) Load current is estimated first 1. uses This is based on the power of electrical equipment (kW or kVA) to calculate the current (ANN) formula. The size of the current is directly related to power, voltage, and also don't rate (also known as power factor and so...
Second Version of the (current) formula: I = V / R If a current I flows through a resistor, and there is a voltage V across the resistor. R can be calculated. Third Version of the (resistance) formula: R = V / I All of these variations of the so called "Ohm's Law" are mathe...
