A simple circuit requires three (3) things: 1  A source of electrical potential difference or voltage. 2  A conductive path which would allow for the movement of charges. 3  An electrical resistance (resistor) which is loosely defined as any object that uses electricity to do work. simple circuit requires three (3) things: 1  A source of electrical potential difference or voltage. 2  A conductive path which would allow for the movement of charges. 3  An electrical resistance (resistor) which is loosely defined as any object that uses electricity to do work.
Power consumption from different mobile devices In electrical engineering, power consumption refers to the electrical energy per unit time, supplied to operate something, such as a home appliance. Power consumption is usually measured in units of watts (W) or kilowatts (kW). The energy used by equipment is always more than the energy really needed. This is because no equipment is 100% efficient
