ABSTRACT:
An electrical circuit is powered by a power supply. There is a first operating circuit which is always energized with electrical power from the power supply. The first operating circuit is operatively connected to a power reducing device. There is a second operating circuit which can, for example, operate the processing portion of a small appliance, such as an electronic calculator. The second operating circuit receives power from the power supply, but is not energized at all times. That is, the second operating circuit is energized with electrical power from the power supply when it is required to run the processing portion of the small appliance. When the small appliance is not run, the second operating circuit does not operate. There is, for an example, an ON/OFF switch on the electrical appliance, to turn the power supply on and off.
