Resistor and capacitor are the key ingredients of many electronic circuit. Here are some reason why:
Power Supply Filter
A capacitor will smooth (filter) the pulsating voltage from a power supply into a steady direct current (DC).
Spike...

Capasitors
There are many kinds of capacitors, but they all do the same thing: store electrons. The simplest capacitor is two conductor separated by an insulating material called dielectric....

Resistors
Resistors come in dozens of size and shapes but they all do the same thing: Limit current (or resist). More abou that later. First, let's see how a typical...

Pulses, Waves, Signals and Noise
Electronics is the study and application of electrons, their behaviour and their effects. The simplest application for electrons are straightforward AC and DC circuit in which a current is used...

How Bipolar Transistor are Used?
When the base of NPN transistor is grounded (0 volts), no current flows from the emitter to the collector (the transistor is "off"). If the base is forward-biased by at least 0.6...

Types of Diodes
Many different kinds of diodes are available. Here are some of the major types:
Small Signal
Small signal diodes are used to transform low current AC to DC, detect (demodulate) radio signals, multiply voltage,...

The Transistor
Transistor are semiconductor devices with three leads. A very small current or voltage at one lead can control a much larger current flowing through the other two leads. This means transistor can...

The Diode
Both P-type and N-type silicon conduct electricity. The resistance of both type is determined by the proportion of holes or surplus electrons. Therefore both types can function as resistors. And...
