To find the Voltage, ( V ):<\/h3>

[ V = I x R ] V (volts) = I (amps) x R (\u03a9)<\/p>

To find the Current, ( I ):<\/h3>

[ I = V \u00f7 R ] I (amps) = V (volts) \u00f7 R (\u03a9)<\/p>

To find the Resistance, ( R ):<\/h3>

[ R = V \u00f7 I ] R (\u03a9) = V (volts) \u00f7 I (amps)<\/p>

Horse Power Calculations:<\/h2>

To find the electric horsepower of a motor, use the equation:<\/p>

Direct Current<\/h3>

Horsepower = (Volts x Amps) * Efficiency\/ 746<\/p>

Single Phase<\/h3>

Horsepower = (Volts x Amps) * Efficiency*Power Factor*1.73\/ 746<\/p>

Three Phase<\/h3>

Horsepower = (Volts x Amps) * Efficiency*Power Factor\/ 746<\/p>

\u00a0<\/h2>

Calculate Power (Watts)<\/h2>

Power (Watts) = Voltage (E) * Current (I)<\/p>

Direct Current:<\/h3>

KiloWatts (KW) = Voltage (E) * Current (I) \/ 1000<\/p>

Single Phase:<\/h3>

KW = E * I * Power Factor (PF) \/ 1000<\/p>

Three Phase:<\/h3>

KW = E * I * PF * 1.73 \/ 1000<\/p>
