Electricity is an essential part of our daily lives, powering everything from small gadgets to large industrial machines. To understand the relationship between voltage, current, resistance, and power in an electrical circuit, Ohm's Law plays a key role. However, calculating these values manually can sometimes be tedious. This is where our Ohm's Law Calculator becomes a valuable tool.

What is Ohm's Law Calculator?

An Ohm's Law Calculator is a simple and efficient tool that helps you calculate one missing electrical property (voltage, current, resistance, or power) in a circuit when the other three are known. It saves time and reduces the chances of calculation errors by providing accurate results instantly.

The calculator is based on Ohm’s Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.

How Our Ohm's Law Calculator Works

1. Input Three Values: Provide three known values from voltage, current, resistance, or power. For example, if you know the voltage, current, and power, you input these into the calculator.
2. Calculation: The calculator uses Ohm’s Law formulas to compute the fourth unknown value.
3. Output: The result is displayed instantly, allowing you to use it for further analysis or practical purposes.

Ohm's Law Formula

Ohm’s Law is expressed using the following equations:

\[ \text{Voltage} (\Delta V) = \text{Current} (I) \times \text{Resistance} (R) \]

\[ \text{Current} (I) = \frac{\text{Voltage} (\Delta V)}{\text{Resistance} (R)} \]

\[ \text{Resistance} (R) = \frac{\text{Voltage} (\Delta V)}{\text{Current} (I)} \]

Additionally, power (P) is related to these values:

\[ \text{Power} (P) = \text{Voltage} (\Delta V) \times \text{Current} (I) \]

\[ \text{Power} (P) = (\text{Current} (I))^2 \times \text{Resistance} (R) \]

\[ \text{Power} (P) = \frac{(\text{Voltage} (\Delta V))^2}{\text{Resistance} (R)} \]
