The Ohm’s Law Calculator is a user-friendly online tool designed to quickly calculate voltage (V), current (I), or resistance (R) based on the classic electrical formula $V=I\times R$. Ideal for students, engineers, and hobbyists, this calculator simplifies complex circuit calculations with instant and accurate results.

Whether you need to find the voltage across a resistor, the current flowing through a circuit, or the resistance value, input any two parameters, and the calculator will compute the third automatically. Featuring a clean interface and responsive design, it’s perfect for use on desktops, tablets, and smartphones.

Enhance your understanding of electrical fundamentals and improve your circuit design efficiency with this free, easy-to-use Ohm’s Law Calculator.
