What is Load Line Analysis | Voltage Gain

What Is Load Line? The output characteristics are determined experimentally and indicate the relation between VCE and IC. However, the same information can be obtained in a much simpler way by representing the mathematical relation between IC and VCE graphically. As discussed before, the relationship between VCE and IC is linear so that it can … 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

Mcqs of Energy band | Electronics | Silicon

Mcqs of energy band, silicon, and energy levels of the 4th chapter which is most important. Usually, this type of Mcqs comes in job tests not all of them but 2 or 3 from this post. these Mcqs of (energy band) are prepared for the learners who are now trying to get a job. Mcqs … Read more

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

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

Conversion of Voltage Source into constant Current Source

Constant Current Source A voltage source that has a very huge internal*impedance as compared with external load impedance or resistance is known as a constant current source. In that case, the load current approximately remains the same when the output voltage changes. Fig. 1.12 (i) illustrates a constant current source. It is a direct current … Read more
