TransformerLess Low Cost DC Power Supply : Resistive & Capacitive

One on the major part of our electronics products is the DC Power Supply that converts mains AC voltage to a lower DC voltage. Usually we use a step down transformer to reduce mains AC voltage to desired low voltage AC and then convert it to DC or we use Switched Mode Power Supplies. But in both cases cost is very high and it takes considerable amount of space. Another Low Cost alternative for Transformer and Switcher based power supply...

Capacitor Codes

Electronics deals with circuits and the one who deals with it should be aware about each and every component used. Not only the component but also its values matters the most. Slight change in value will lead to terrible errors, so to avoid that problem one must be aware of selecting the component values and to check whether it is right or not. Most of us is aware about resistor color code but only few know to identify the capacitance values....

Camouflage objects using Nano-Mirage Effect

Everyone of us was astonished by seeing the camouflage effect in the James bond movie. It was a brilliance of visual effects. But ever wondered if it works for real. Yes!!! The scientists are on the verge of the discovery of it. [youtube video_id="UPFBPxFDFB8" width="880" height="495"] The mechanism has now been developed by researchers at the University of Texas at Dallas. They were able to detect a unique characteristic in carbon nano-tubes with a kind of mirage effect which helps to switch on and turn...

Zener Diode Voltage Regulator

Zener Diode is a general purpose diode, which behaves like a normal diode when forward biased. But when it is reverse biased above a certain voltage known as zener breakdown voltage or zener voltage or avalanche point or zener knee voltage the voltage remains constant for a wide range of current. Clarence Zener is the scientist who discovered this electrical property and the device is named after him. Zener Diode Ordinary diodes will not have any significant current (only leakage current ) when reverse biased below...

X and Y Rated Capacitors

Capacitors are passive two terminal electronic components that has a wide variety of applications from oscillators to power supply applications. One of the important application of capacitors is power line filtering which is used in many electronic devices and appliances. Capacitors used for these applications are categorized as X and Y rated capacitors. These capacitors are also known as EMI/RFI suppression capacitors or AC Line filter safety capacitors. These capacitors can supply various protective measures and operational insulation to various electrical and electronics equipment. X...

IC LM 723 Voltage Regulator

The 723 voltage regulator is a voltage regulator commonly used for series voltage regulator applications. With an ability to provide upto 150 mA of current to the load, but this can be extended to any range with the help of some extra circuit involving common components like transistors. It also comes with comparatively low standby current drain, and provision is made for either linear or foldback current limiting.

Bridge Rectifier

Rectifier A rectifier is a device that converts AC into DC. The power available to us is in the form of AC. But almost all electrical equipments work on DC. So we need a converter that converts AC into DC. We employ a rectifier circuit for this purpose. Rectifiers are basically classified into Half Wave and Full wave according to the cycles (either Half of a cycle or Full) that are rectified. Among these the bridge rectifier is the most efficient...
