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 | Types | Properties | Applications

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 | Properties | Efficeince | Ripples

FULL WAVE RECTIFIER: In full wave rectifier, current flows through the load in the same direction for both half cycles of ac input voltage .it allows unidirectional (one way) current through the load during the entire 360 degrees of the input cycle, whereas a half-wave rectifier allows current through the load only during one 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

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

Maximum Power Transfer Theorem | Applications

Whenever the load is connected across a voltage source, power is transferred or moved from the source to the load. The amount of power transferred will depend upon the resistance of the load. If the resistance of load RL is made equal to the internal resistance Ri of any source, then maximum power is transferred … Read more
