Ohm S Law Formula Chart

Simple to use ohm s law calculator.

Ohm s law formula chart. Just enter 2 known values and the calculator will solve for the others. Ohm s law pie formula chart. Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. When resistance decreases current increases.

For a better understanding of the relation between various parameters we can combine all the equations used to find the voltage current resistance and power into a simple ohm s law pie chart as shown below. The rate at which work is done when one ampere a of current flows through an electrical potential difference of one volt v. Power is measured in watts and is defined as. Calculate power current voltage or resistance.

The chart below left shows the relationship between voltage current and resistance. The pie chart is similar to the voltage current and resistance formula wheel. Ohm s law formula paichart. Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship.

Ohms law pie chart to help us understand the the relationship between the various values a little further we can take all of the ohm s law equations from above for finding voltage current resistance and of course power and condense them into a simple ohms law pie chart for use in ac and dc circuits and calculations as shown. Below are the formulas for these calculations. Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in.
