... 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...
