History of Artificial Intelligence ( AI )

What Is History Of Artificial Intelligence? The gestation of artificial intelligence (1943-1955) History of Artificial Intelligence: The first work that is now generally recognized as Artificial Intelligence was done by Warren McCulloch and Walter Pitts (1943). They drew on three sources: knowledge of the basic physiology and function of neurons in the brain; a formal … Read more

Common Emitter | Common Collector Connection

What is Common Emitter? In this circuit arrangement, input is applied between base and emitter and output is taken from thecollector and emitter. Here, emitter of the transistor is common to both input and output circuits and hence the name common emitter connection. Fig. 8.16 (i) shows common emitter npn transistor circuit whereas Fig. 8.16 … Read more

What is Transistor | Definition | Principle | Properties

What is Transistor ? When a third doped element is added to a crystal diode in such a way that two pn junctions are formed, the resulting device is known as a transistor. The transistor—an entirely new type of electronic device—is capable of achieving amplification of weak signals in a fashion comparable and often superior … Read more

What is PN Junction | Properties of PN Junction

What is PN junction ? When a p-type semiconductor is suitably joined to n-type semiconductors, the contact surface is called PN junction. Most semiconductor devices contain one or more PN junctions. The PN junction is of great importance because it is in effect, the control element for semiconductor devices. Thorough knowledge of the formation and … Read more

Hole Current | Intrinsic & Extrinsic Semiconductor

What is Hole Current ? At Normal room temperature, few of the covalent bonds in pure semiconductor material break, setting up free electrons. Under the effect of the electric field, these free electrons constitute an electric current. At the same time, another current – the hole current – also flows in the semiconductor. When a … Read more

MCQs of Thyratron | Gas filled tube

Mcqs of Thyratron and gas-filled tube of the 3rd chapter which are most important and usually this type of Mcqs of thyratron comes in job tests not all of them but 2 or 3 from this post. these Mcqs of thyratron are prepared for the learners who are now trying to get a job. A … Read more

Cold Cathode Gas Diode | Applications of Glow Tubes

Cold-Cathode Gas Diode Fig. 3.6 shows the cut-away view of the cold-cathode gas diode. It essentially has two electrodes, anode, and cathode mounted fairly close to each other in an envelope filled with few inert gases at small pressure. The anode is in the shape of a thin wire whereas cathode is of the cylindrical … Read more

Half Wave rectifier | Properties | Frequency| Ripples

What is a Half Wave Rectifier? A half-wave rectifier can be explained as a type of rectifier that only passes one half-cycle of an AC voltage waveform to pass, blocking the remaining half-cycle. Half-wave rectifiers are normally used to convert AC power to DC power, and only require one diode to construct. A simple Half … Read more

Thevenin’s Theorem | Properties | Problems

Sometimes it is desirable to determine a particular branch current in a circuit as the resistance of that branch is changing while all other resistances and voltages remain constant. For instance, in the circuit shown in Fig. 1.23, it may be required to determine the current through RL for five values of RL, let that … Read more
