LongRun was based primarily on aggressively reducing the clock frequency and voltage supplied to the processor, in order to reduce active power consumption.

Thus, the cartridge "modulates" an external voltage supplied by the (special) preamp.

Some programs allow the user to manually adjust the voltages supplied to the CPU, which reduces both the amount of heat produced and electricity consumed.

Additionally, at lower temperatures, the voltage supplied to the chip could be safely increased, which also improved the instruction rate-again, with no additional configuration.

A variable-frequency drive controls the operating speed of an AC motor by controlling the frequency and voltage of the power supplied to the motor.

The inherent flaw in this method was that turning off a single lamp (or other electric device) affected the voltage supplied to all others on the same circuit.

Reducing the voltage supplied to the CPU below the manufacturer's recommended minimum setting can result in system instability.

Making sure that the voltage, frequency and amount of power supplied to the loads is in line with expectations is one of the great challenges of power system engineering.

Low voltage refers to electricity supplied to and derived from the house batteries, typically 12 volts DC.

These crossings are fitted with equipment to change the voltage supplied to the overhead wiring depending on the vehicle using the crossing at that point in time.
