    RMS Voltage Calculator

    An online calculator can convert other measures of AC voltage into RMS. Input Peak Voltage (Vp) Peak-to-Peak Voltage (Vpp) Average Voltage (Vavg) Volts (V)     Output RMS Voltage(Vrms) Volts (V) How do you calculate RMS Voltage? RMS voltage stands for root mean square voltage. It is a measure of direct rather than alternating current. Direct current is easy to…

    Stepper Motor Calculator

    A stepper motor calculator is a simple online tool that allows one to figure out the maximum power, minimum time per step, and the maximum speed of a stepper motor. After I know the current, inductance, voltage, and steps per revolution, then I can automatically calculate the motor’s speed, time, and power. Inputs Current (Imax) Amps (A) Inductance (L) milliHenry…
