anwaralijamali16@gmail.com A light-dependent resistor is also known as a photoresistor, photoconductor, and photocell. An LDR is one kind of resistor whose resistance differs depending on the amount of light falling on its surface. When the light falls on the resistor, then the resistance modifies. These resistors are often used in many circuits where it is needed … Read more
In this article, we are going to show you two way light switch. A 2-way switching means you can control operate appliances like bulb water pump etc by using two switches at different locations, generally used to control water pump from different stories of a house. The 2-way switch can be ON/OFF from any of … Read more
A neon bulb contains neon gas at low pressure, enveloped in a glass capsule. Neon lamp Circuits emit light when electric light passes through the gas. These lamps widely used in neon signboards. The neon lamp is composed of a sealed glass bulb containing two electrodes and a low-pressure noble gas mixture. The gas immediately … Read more
A capacitor is an electronic component distinguish by its capacity to store an electric charge. A capacitor is a passive electrical part which can store energy in the electric field between a pair of conductors (it is called “plates”). In simple words, we can call that a capacitor is a tool used to store and … Read more
The Diode is an electrical part that allows the flow of current only in one direction. In-circuit diagrams, a diode is represented by a triangle with a line across one peak. Pin configuration of the diode. In this article, we are going to explain in detail diode and types. Diode and types: There are ten … Read more
The 2SA1943 transistor is a PNP transistor originally from Toshiba. Due to the transistor high current gain and collector current it is very generally used in AF amplifiers or High power audio circuits. But now this Transistor is entirely from Toshiba and it has been changed with TTA1943, However, still the good and old transistor … Read more
The 2Sa1015 is PNP transistor which is mainly used for general purpose amplification. This transistor consists of three terminals: emitter, base and collector. N layer represents the base side and P layers represent emitter and collector. In the market 2sa1015-y, 2sa1015 and a1015 are available. 2sa1015 pinout The pinout of this transistor is given below … Read more
Doorbell Circuit using IC 555 and CD4017: The bell is a very common and useful electronic device used in houses, offices, etc. Among electronics students and hobbyists, the doorbell circuit project is very popular. So in this tutorial, I am going to build a doorbell with 555 (timer) IC. The main feature of this doorbell … Read more
BC549 transistor: This is an NPN transistor so the collector and emitter will be on when supply small current to base. BC549 is a low current transistor so the max amount of current that could flow through the Collector pin (Ic) is 100mA, so we cannot connect loads that use above 100mA and load voltage … Read more
2n2907 transistor is PNP Bipolar transistor available in metal can package, having a high 600mA value of current with low voltage of 40v. Transistor 2N2907 being is fully biased when positive current is given to base. This transistor is having gain value of 100-300 which shows the amplification capacity. It is also used for the … Read more
