This formula calculates the total current for all three wires in a three-phase system. You will need to divide the result by 3 to find the current for a single wire in the circuit. Once you identify how much current you’re working with, you can use ourwire ampacity calculatorto determin...
Current Divider - Online Calculator An electric current divider outputs a current that is a fraction of the input current. A current divider is a linear circuit that produces an output current that is a fraction of the input current. Current is split between the branches of the divider. The ...
This calculator determines the energy rating of an inrush current limiter. It’s particularly useful in electrical circuits to understand the energy dissipation characteristics of a limiter. Formula:Energy = ½ × Capacitance × (Voltage)2
Use this calculator to determine the current in microamp, milliamp or amp units in a direct current (DC) electrical circuit with a specified voltage and resistance. Two conversion scales show how the current in an electrical circuit changes as voltage or resistance is changed independently, whilst...
Use this calculator to determine the current generated by a direct current (DC) electrical circuit for a specified power and resistance I=√(P/R)
Motor-rated power in HP or kW. (Mandatory) Input supply voltage. (Mandatory) Motor Efficiency as per nameplate – (if known). Rated power factor (if known).After entering the required data, click on the “Calculate” button to find out the required fuse rating, Circuit Breaker rating, co...
Motor-rated power in HP or kW. (Mandatory) Input supply voltage. (Mandatory) NEMA code. (Mandatory) After entering the required data, click on the “Calculate” button to find out the locked rotor current of the motor. The appropriate selection of fuses, circuit breakers, overload relays, ...
A microstrip is a flat conductor separated by an insulating dielectric from a large conducting ground plane and is mostly manufactured from a printed circuit board. It is similar in function to capacitors and inductors but only for very high frequencies. As such, microstrips are also subject to...
Sierra Circuits’ via current capacity and temperature rise calculator is designed to assist you in building the perfect PCB vias. This tool calculates all the predominant factors associated with a circuit board via design. Many things might go wrong if these parameters are not carefully chosen. Us...
