A digital circuit requires a power supply to provide a constant and stable source of electric power to all devices. As discussed above, electric power is derived from the basic electrical forces that charged particles (e.g., protons and electrons) exert on one another – namely, electrons are repelled by other electrons, and attracted to more electrically positive areas where there are relatively fewer electrons. The vast majority of charged particles are found in ordinary matter bound in electrically neutral atomic structures (that is, most particles are found in structures that have an equal number of positive and negative particles). Some electrically neutral conducting materials (like metals) contain electrons that are not so tightly bound to their host atoms. If a voltage source is applied to these materials, the lightly bound electrons will move away from the concentrated source of electrons on the negative side of the supply towards the electrically positive side of the supply. A “power supply” in a digital circuit provides a local, contained imbalance of electrons that provides a voltage source that can do useful work, such as transmitting information through a conductor from one device to another. A digital circuit allows a controlled flow of electrons from of the negative to positive side of the power supply, but only via the paths designed into the circuit. As electrons flow to and from the devices in a given circuit, they can change device properties in useful ways.
By Sasha Sara. Diagram. Published at Wednesday, December 27th 2017, 05:29:58 AM. An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. Furthermore, a closed circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.

Hence the word electricity is derived from the word electrons. A battery itself doesn’t work, if you hold it up in air, there would be no passage of electric current. Hence you need a circuit. In Simple terms an electronic circuit is a closed pathway for electrons to flow.

Generally, amplifiers can be sub-divided into two distinct types depending upon their power or voltage gain. One type is called the Small Signal Amplifier which include pre-amplifiers, instrumentation amplifiers etc. Small signal amplifies are designed to amplify very small signal voltage levels of only a few micro-volts (μV) from sensors or audio signals.

This is because the diode symbol was invented by engineers, who predominantly use conventional flow notation in their schematics, showing current as a flow of charge from the positive (+) side of the voltage source to the negative (-). This convention holds true for all semiconductor symbols possessing “arrowheads:” the arrow points in the permitted direction of conventional flow, and against the permitted direction of electron flow.
