TV vs Radio Ellen Bullard p.5 Isn’t it amazing that people who lived two hundred years ago didn’t have radios or televisions? Today it is difficult to imagine life without these two forms of communication. These technological wonders have many similar characteristics. As you will see‚ they are also quite different. To start with‚ both radios and televisions need a source of power in order to run. If you have no electric socket or batteries on hand‚ you won’t get to watch TV or listen to the radio

Thermionic valves which were once used in computers‚ radios‚ and TVs were replaced by transistors. Compared to thermionic valves transistors: ~Had much smaller sizes (miniaturization) ~Much cheaper and more reliable ~Used less power When transistors were first developed they were about 0.5 cm3 in volume It was found that transistors could also be miniaturized by using silicon doped with arsenic/gallium. Several million transistors could now be placed on area of 1cm3. This had enormous consequences

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient
