What is Basic

This section cover question about what is basic electronics, what is use of different parts of electronic, circuit design fault and fundamental theory of electronics. solution of some critical circuits and hits and tips of electrical theory.

What are the pros and cons of BJT versus FET transistors?

For pros and cons of BJT versus FET transistors first we needs to know whats its use in circuit and then we can understand benefit and losses of BJT vs FET transistors. Use of Bjt: this is the best device in…

What advantage does the alternating current have on direct current?

Ac is much easier to handle, because you can use a transformer to change the voltage, which is much cheaper, less complicated and more reliable than a dc voltage converter for a given capacity. it is the most important factor…

What is DB gain?

In electronics, amplification is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of an input signal to the output port by adding the converted energy from a power source to…

What is the use of transformers?

Transformer has its own important in the present arena as per the requirement and application the transformer has used as Uses and application of transformer The most important uses and application of transformer are: Can rise or fall the level…

What is a Varicap diode?

In electronics, a varicap diode, a varactor diode, a variable capacitance diode, a variable reactance diode or an adjusting diode is a diode type designed to exploit the voltage-dependent capacitance of an inverted p-n junction. The varators work in a…

What is FET?

What is FET. Fet (field effect transistor) is the second major type of transistor. the first major type is bjt (bipolar junction transistor).fets are uni polar devices because, unlike bjts that use electrons and loop currents, they operate only with…

What’s the point of fusing?

The point of fusing. The fuse function is usually to prevent fire – that is, the basic protection offered by the fuse – between the power supply and the appliance may be several feet or meters of cable – if…

How does the electric fuse protect the electrical alliance?

Electric fuse protect the electrical alliance Fuse wire is used to protect a circuit.in our home wiring, we have used a fuse. all electrical materials we have used in our home wiring such as switch boards, switches, cables etc. have…

What is the purpose of the fuse box and relay in the car?

Purpose of the fuse box and relay in the car. Fuses limit current and protect against fire. Relays allow small control signals to run heavier equipment using larger signals, eg. headlights, starter, air conditioner. Small control signals can come from…

Ohm’s Law

Ohm’s law states that the current is directly proportional to the voltage and vice versa proportional to the resistance. This means that as the voltage increases, the current increases increase at the same rate. When the voltage decreases, the current…

Atomic Structure

The smallest building blocks of matter are Called atoms. All atoms consist of three Basic components: the proton, the neutron and the Electron See illustration. Different Number and arrangement of protons, Neutrons and electrons give atoms differently Properties that make…

Types of Electricity

Types of Electricity Direct Current Current flowing in one direction only is called direct current. The letters “DC” Represent direct current. A battery generates direct current. The voltage source behind it This DC current has the same polarity all the…

Power

Power is the rate at which the work is done or the electricity generated or consumed. The unit of measurement is the watt, and the letter identifier is “P”. electrical Devices are measured in watts. Power is calculated by multiplying…
