This calculator calculates values using Ohm’s law and Joule’s first law determining the relationship between current, voltage, power, complex power, impedance, and resistance for AC and DC circuits. It determines one or two unknown values from the two known values. Example 1: A 5-ohms resis...
What the equation for power is; How to calculate power; and Ohm's law for anisotropic materials. Prefer watching rather than reading? Check out our video lesson on resistors and Ohm's law here: Watch this on YouTube Ohm's Law Formula Ohm's Law is one of the basic laws of physics....
Calculate circuit parameters using Ohm's Law Enter any two known values and press "Calculate" to solve for the others. Voltage (V) Current (A) Resistance (Ω) Power (W) Overview When we talk about fundamental circuit theories, Ohm's Law is the most fundamental of them all. This law...
If only one is known, you need resistance or the other value (current or voltage) to compute power using other laws like Ohm's Law (V = IR). What does a negative power value signify?A negative power value usually indicates that a component or system produces or exports power rather ...
Our calculator is based on the two laws that describe simple electrical circuits. One of them - Watt's law - states that: Power = Voltage * Current - in symbols: P = V * I. This power equation, as well as the power unit, were named after James Watt - a Scottish engineer. One wa...
The output voltage from a potential divider with two resistorsR1= 1000 ohmsandR2= 2000 ohmsand input voltage12 Vcan be calculated as Uout= (12 V) (2000 Ω) / ((1000 Ω) + (2000 Ω)) =8(V) The current through the potential dividerR1andR2(ex. output current) can be calculated by...
