Gas Filled Tubes | Conduction in a Gas

INTRODUCTION OF GAS-FILLED TUBE In the vacuum tubes, the electrons pass from the cathode to anode in a vacuum. In that type of tubes, extreme care is taken to generate as perfect a vacuum as possible to prevent ionization of gases and the resulting large uncontrolled currents. It may be mentioned here that the logic … Read more

What is Diode | Diodes Working | Zener | LED | Varactor, Schottky, Tunnel

What is diode ? A diode can be discussed as a two-terminal electronic device that only conducts current in one direction (so long as it is working within a required voltage level). An ideal diode always has zero resistance when it is forward biased or one direction, and infinite resistance in the reverse bias. basically … Read more

Full wave Rectifier | Bridge | Center tap| Properties | Efficiency | Ripples

FULL WAVE RECTIFIER: Defining Full Wave Rectifiers A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC. Unlike half wave rectifiers that utilize only the half wave of the input AC cycle, full wave rectifiers utilize the full cycle. The lower efficiency of the half … Read more

Norton’s Theorem | Chassis and Ground| Properties

What is Nortons Theorem Fig. 1.38 (i) shows a circuit enclosed in a box with A and B terminals brought out. The network in the box may have any number of e.m.f. sources and resistors connected in any manner. But according to Norton, the complete circuit behind A and B terminals can be changed by … Read more
