How To Use an Ohm’s Law Calculator
Using an Ohm’s law calculator is a fun and exciting way to calculate the basic electrical parameters of a circuit. Simply input the known values of voltage (V), current (I), resistance (R), or power (P), and the calculator will use the Ohm’s law equation to solve for the unknown value.
The equation is V = I * R, I = V / R, R = V / I, or P = V * I. With a few clicks, you can easily determine the necessary resistance, voltage, or current in an electrical circuit design, measure the resistance of an electrical component, estimate the power consumption of a device, and much more!
Whether you’re a seasoned electrical engineer or just starting out, using an Ohm’s law calculator is a great way to deepen your understanding of electricity.
