Enter any two inputs and click on Calculate button
How to use this Ohms Law Calculator 🤔
There are input fields for Voltage \((V)\), Current \((I)\), Resistance \((R)\), and Power \((P)\). Enter any two inputs and click on Calculate button.
The calculator uses the \( V = I \cdot R \) \( P = V \cdot I \) formula, substitues given values, and calcuates the missing value(s).
A missing value is calcuated and displayed in the input field. Also, the caculation is displayed under the input section.
What is Ohm's Law
Ohm's Law is a fundamental principle in electronics and electrical engineering that states the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is typically expressed as:
\[ V = I \cdot R \]
Where:
\(V\) is the voltage in volts (V)
\(I\) is the current in amperes (A)
\(R\) is the resistance in ohms (Ω)
Calculating Power, Voltage, Current, and Resistance
Power (P) in an electrical circuit is given by the product of voltage and current:
\[ P = V \cdot I \]
We can rearrange Ohm's Law to solve for voltage, current, and resistance as follows:
\[ I = \frac{V}{R} \]
\[ R = \frac{V}{I} \]
\[ V = I \cdot R \]
