This tool calculates the equivalent resistance of several resistors connected either in series or in parallel. Enter each resistor value with its unit (Ω, kΩ, or MΩ), and the calculator will apply the correct formula automatically. How It Works Resistors in Series When resistors are connected end-to
Calculate DC and AC voltage from current, resistance, power, impedance, or power factor. Supports Ohm’s Law, real/reactive power, and RMS values for engineers, technicians, and students. Known Parameters Formula Circuit Type Notes Current (I), Resistance (R) V = I × R DC / AC resistive Ohm’s Law; va
Calculate voltage drop in DC and AC circuits using key electrical parameters. "Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. According to Annex G – IEC 60364–5–52." Key Parameters Current Type Direct Current (DC): Current flows con
This tool calculates the rating of protective devices (circuit breakers) for electrical circuits according to IEC 60364-4-43, providing protection against overloads and short circuits. Suitable for industrial, commercial, and building electrical design. Parameter Description Current Type Select the
Determine the minimum conduit diameter for a given cable bundle using IEC 60076 fill rules. Supports PVC, steel, and raceway types. Ensures pullability and regulatory compliance. This tool calculates the minimum required conduit external diameter to safely accommodate a cable bundle, based on the ma
