# Ohms Law - The Definition Of Power Equations

**Allcalculator.net** provides a convenient **Ohm's Law calculator** for determining the connections between voltage, current, and resistance across a certain conductor. Ohm's law calculator can be quite helpful in researching electronic circuits and calculating power dissipation.

**Current Flow vs. Electron Flow**

If you often conceive of electricity as the flow of electrons from lower to higher voltage, you should keep in mind that while designing and analyzing circuits, we presume that current is the passage of electric charge from higher voltage to lower voltage.

**Current - Kirchhoff's Law**

Kirchhoff's current law, sometimes known as KCL, asserts that the total current entering and departing a node are equal. We can determine an unknown current using known currents thanks to KCL.

**Voltage - Kirchhoff's Law (KVL)**

Kirchhoff's Voltage Law, which German scientist Gustav R. Kirchhoff developed in 1847, may be summarized as follows:

"All voltages in a loop's algebraic total must equal zero."

By algebraic, I mean taking into consideration both magnitudes and signs (polarities). Any path that is taken from one point in a circuit around to other places in that circuit, and then back to the starting point, is referred to as a loop.

**Ohm's Rule**

According to Ohm's law, a resistive component's current is equal to the component's voltage divided by its resistance.

Sometimes, it might sound limiting to understand the values and determine the same manually. To avoid all these buzzes, you can use the online ohms calculator where all you need to input is your voltage, resistance, current, or power any of these values and you will be getting the results almost immediately.

**How is power calculated?**

Use our Ohm's Law calculator if you are still unsure how to calculate the power using the offered formulae or if you just want to save time. This tool's structure is simple; just enter any two of the four values to get the other two. The power formula and Ohm's Law formula serve as the foundation for the Ohm's law calculator. To calculate the value of power, simply type:

Voltage (expressed in volts) (expressed in volts)

Current (expressed amperes) (expressed in amperes)

You will then receive two numbers from the Ohm's Law Calculator: resistance, expressed in ohms, and power, expressed in watts. Use our wattage to convert this value to another unit if necessary.

**Powering up **

Now that you have gotten an idea about how the ohms calculation is done. You can use the online ohms calculator to derive the result and define the strategy behind it manually.
