... only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. [12] Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ... light source. It is a pn-junction diode, which emits light when activated. [14] When a suitable voltage is applied to the leads, electrons are able to recombine with electro...

It was programmed by and stored data on cards with holes punched in them, appropriately called punch cards. This machine was extremely useful to managers that delt with large volumes of good. With Babbage's machine, managers could more easily calculate ... punched-card system that could automatically read information on cards without human (Dolotta, 1985).
