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.
A Parallel circuit is one with several different paths for the electricity to travel. It's like a river that has been divided up into smaller streams, however, all the streams come back to the same point to form the river once again. The parallel circuit has very different characteristics than a series circuit.For one, the total resistance of a Parallel Circuit is NOT equal to the sum of the resistors (like in a series circuit). The total resistance in a parallel circuit is always less than any of the branch resistances. Parallel circuit is one with several different paths for the electricity to travel.
