Class C Amplifiers You will recall that most AF amplifiers use cathode bias. The audio amplifier tubes are operated ad Class A or Class B, because we are interested in obtaining good fidelity. The Class A amplifier sacrifices efficiency for fidelity. In the case of an...
Introduction Nickel-Cadmium batteries can save much time and money when they are used to replace other non-chargeable dry batteries. They must however, be treated in a suitable manner or they could become useless within just a few weeks. I have had many people come to...
Primary Cell: When dissimilar materials like zinc and carbon(or copper used in place of carbon)were immersed in a bath of acid solution(suphuric acid diluted in water), chamical action produced an electromotive force between the zinc and the carbon. The materials...
When a diode is connected in series with other circuit components, current can flow in only one dirction in all of these components. This characteristic makes the diode a useful device for "rectifying", or converting AThe diode vacuum tube has only 2 electrodes - a...
Knowing what a diode is, or how a triode works is of little use unless you have some practical knowledge of how it can be applied within a circuit. We are going to begin with a VERY basic schematic of an early transmitter. When ever we are looking at a schematic...
As we have studied the effects of electricity flowing through wires, and have discussed resistors, coils, and metering devices. Both resistors and coils have a restricting effect on the flow of current. We also discussed how a coil has more resistance to AC than it...
Almost 20 centuries ago, an ore called magnetite was found and was called “lodestone” or leading stone. Name magnetism derived from the name of the place from where these type of rocks were found. The lodestone later was given name of magnet. Lodestone & Magnet:...
Sometime over the years, some bright soul determined that it would be difficult to draw a picture of every component that you decided to put into a circuit. However, they needed a way to tell their colleagues about discoveries and accomplishments. So a system was...
