Ohm Wheel Calculator
Interactive Ohm law wheel calculator showing relationships between voltage, current, resistance, and power.
Formula
V=IR | P=VI | P=I²R | P=V²/R
Ohm's law and the power law. Enter any 2 values and the calculator finds the other 2.
Frequently Asked Questions
What is Ohm's Law and how is it applied?
Ohm's Law states V = I * R, where V is voltage (volts), I is current (amperes), and R is resistance (ohms). It is the foundation of circuit analysis. Rearranged: I = V/R to find current, R = V/I to find resistance. Power is calculated as P = V * I = I^2 * R = V^2 / R.
