Basic Circuit Laws
Every basic circuit laws calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
3 calculators in this section
- Ohm’s Law CalculatorEnter any two of voltage, current, resistance and power and get the other two, with units scaled automatically from µA to kA and mΩ to MΩ — plus the full wheel of twelve Ohm's-law formulas.
- Series and Parallel Resistor CalculatorTotal resistance of up to six resistors in series or in parallel, with the voltage across and current through each one, the power every resistor has to get rid of, and the nearest single standard value to the combination.
- Voltage Divider CalculatorOutput voltage of a two-resistor divider, how much a load pulls it down, the current and power in each resistor — and a design mode that picks a standard E24 or E96 pair for the voltage you want.
