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)
