ohm’s law pie chart To help us understand the relationship between the various values even better, we can condense all of the Ohm’s Law equations from above for finding Voltage, Current, Resistance, and, of course, Power into a simple Ohms Law pie chart for use in AC and DC circuits and calculations, as shown.

- P = Watts
- watts = volts ^ 2 / Ohms
- Watts = Amperes^ 2 X Ohms
- Watts = Volts X Ampere
- I = Amperes
- Amperes = Volts / Ohms
- Amperes = Watts / Volts
- Amperes = In Root Watts / Ohms
- E = Volts
- Volts = In Root Watts X Ohms
- Volts= Watts / Amperes
- Volts = Amperes X Ohms
- R = Ohms
- Ohms = Volts / Amperes
- Ohms = Volts^2 / Watts
- Ohms = Watts / Amperes ^ 2
The movement of current on a wire or conductor is analogous to the flow of water down a canal. On the top of a conductor, current flows from negative to positive. Present is measured in amperes (A) or amps (A).
The voltage difference between two points in a circuit is known as the difference in electrical potential. That is the force or drive that causes current to pass through a circuit and is represented in (V) volts.
The amount of current that flows through a part is determined by its resistance. Resistors are used to regulate voltage and current.
A very high resistance allows only a limited amount of current to get through. A very low resistance allows a broad current to run. unit of measurement for resistance is ohms.
Power is defined as the sum of current multiplied by the voltage level at a given point, expressed in wattage or watts.

What is Ohm’s law diagram
According to Ohm’s theorem, current across a conductor is strictly proportional to the voltage disparity through it. V = I R, where V denotes voltage, I denotes current, and R denotes resistance. The circuit diagram for confirming Ohm’s law is seen below.
