Portable space heaters are small, electric resistance heating units. Regardless of the shape, size or type of electric heating element found in an electric space heater, virtually all power drawn is converted into heat. The cost of operating an electric heater depends on how much heat the unit is delivering.ortable space heaters are small, electric resistance heating units.

Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film.
SERIES-PARALLEL CIRCUIT - A circuit in which some of the circuit components are connected in series and others are connected in parallel. SHORT (OR SHORT CIRCUIT) - This occurs when one part of a circuit comes in contact with another part of the same circuit, diverting the flow of current from its desired path. SHUNT - A conductor joining two points in a circuit so as to form a parallel circuit through which a portion of the current may pass.
