Ohm's law calculator ►Ohms calculationsThe resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A):The resistance R in ohms (Ω) is equal to the squared voltage V in volts (V) divided by the power P in watts (W):...
The relationship between voltage and current is defined (in ohmic devices like resistors) by Ohm's Law. Ohm's Law is analogous to the Hagen–Poiseuille equation, as both are linear models relating flux and potential in their respective systems. Electric current (I) is a rate of flow and is...
(Source: Ohmslawcalculator) Using the appropriate formula from the wheel, you can calculate whatever measurement you need using units you already have. For example, if a device consumes 4000W when running and requires 240V, you can use this formula to find intensity (represented by I in the ...

We can get the Ohms into the act too. Just combine this equation with Ohm's law. Charge flow is caused by volts pushing against ohms, so let's get rid of amps in the above equation and replace it with voltage and ohms. This forms the equation below. Notice: increasing the voltage wi...
How to Calculate Watts Using Amps and Ohms By usingOhm’s Law, you can also find the power in watts given the current in amps and theresistancein ohms using this formula:[1] P(W)= I(A)2× R(Ω) Thus, the powerPin watts is equal to the product of the square of currentIin am...
Converting voltage, measured in volts, to power measured in watts is easy using theWatt’s Lawpower formula. Watt’s Law states thatcurrentis equal topowerdivided byvoltage. Multiplying both sides of this relationship by voltage, we can change this formula to also state that power is equal to...
resistance of the circuit element may be known. By using Ohm's Law ( V = I x R) it is possible to calculate the power if either the voltage or current is known. For example the mains voltage may be known to be 250 volts and the element resistance may be known to be 62.5 Ohms. ...
In some instances, you might know a component’s resistance (measured in ohms) but not the current. In such cases, Ohm’s Law and the power formula can be combined: Watts (W) = Volts (V)2/Resistance (R) For example, a component with a 4 ohms resistance operating at 12 volts would...
Thanks in advance Regards Reply LearnMetrics Hello Michael, you’re correct; the Ohms law is the basic equation. Inductive loads like pool pumps that use 3 phase current? Sure. The equation for 3 phase current is I (Amps) = 1000 x kW / (√3 x VL x P.F.); where VL is the RMS...
