Education for the student and the electrician.

Power triangle and ohm's law triangle.

The equations are displayed in each calculation.

It has unit conversion when entering the data.

Units can be ohms, volts, amps, watts.

Voltage:

- CURRENT * RESISTANCE

- POWER / CURRENT

- √ (POWER * RESISTANCE)

Stream:

- VOLTAGE / RESISTANCE

- POWER / VOLTAGE

- √ (POWER / RESISTANCE)

Resistance:

- VOLTAGE / CURRENT

- VOLTAGE² / POWER

- POWER / CURRENT²

Power:

- VOLTAGE * CURRENT

- CURRENT² * RESISTANCE

- VOLTAGE² / RESISTANCE

The units:

Voltage: milliVolt (mV) - Volt (V) - kiloVolt (kV)

Current: milliAmp (mA) - Amp (A) - kiloAmp (kA)

Resistance: milliOhm (mΩ) - Ohm (Ω) - kiloOhm (kΩ)

Power: milliWatt (mW) - Watt (W) - kiloWatt (kW)
