Ohm's Law Calculators
Calculate voltage, current, resistance, and power using Ohm's Law and related formulas.
Ohm's Law Calculator
Solve for voltage, current, or resistance using V=IR. Enter any two values to find the third.
Electrical Power Calculator
Calculate electrical power using P=VI, P=IĀ²R, or P=VĀ²/R. Supports all combinations of voltage, current, and resistance.
Voltage Divider Calculator
Calculate output voltage of a resistive voltage divider given R1, R2, and input voltage. Ideal for sensor circuits and bias networks.
Current Divider Calculator
Calculate branch currents when resistors are connected in parallel. Uses the current divider rule.
Series & Parallel Resistance Calculator
Calculate total resistance for resistors in series or parallel combinations. Enter multiple values separated by commas.
