You probably already know that you can model the direct current (DC) with the help of Ohm's law. This tool will help you calculate the load on a circuit to see if it is excessive. Supply wiring must be rated to carry at least the amps shown as MCA. AC Power Calculator. If the load is purely resistive, the two quantities reverse their polarity at the same time. The formula for calculating the output voltage is based on Ohms Law and is shown below. Enter the total amperage on the circuit; also enter one half of the total length of the circuit. Design with our easy-to-use schematic editor. We strongly suggest that you use the results here as they are intended, estimates. An Electrical circuit consists of three major electric components of a Resistor, an Inductor and a Capacitor connected in series or in parallel AC - Active, Reactive and Apparent Power - Real, imaginary and apparent power consumption in AC circuits; Asynchronous Induction Motors - Electrical Data - Electrical motor data - nominal current, fuse, start ampere, contactor and circuit breaker of asynchronous induction motors Inductive Reactance from Inductance Calculator Formulas and equations Inductive Reactance Calculator Enter the values of Frequency & Inductance and click on Calculate. ac circuit calculator. Fig 9. heater. Also includes special condition buttons for nipples, AC/MC cable, equipment rated for continuous loads, and circuit is for receptacles for cord and plug connected equipment. When the output is at logic high level, diode D2 will conduct and the current will pass through diode D1, R3 to the base of transistor Q1
