No matter what are the qualities of Apple products, but our money is not less valuable than Apple. Think logically while purchasing Apple products. First things first…
Apple is such a cunning group of software and hardware products, that they work very slowly.
They upgrade their products, with hardware as well as software upgrades, with small pinches and the customer has to wait till new upgrade.
They confess to provide the upgrade in “next week”, particularly on their backbone apps “iTunes”, but that “next week” comes after around 3 to 4 months time.
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor. The dissipation factor of a capacitor is the the ratio of its resistance to its capacitive reactance. The Schering Bridge is basically a four-arm alternating-current (AC) bridge circuit whose measurement depends on balancing the loads on its [...]
When sudden and strong sun flares appear, these are also known as the bright spots on the solar surface or in the corona of the sun, this produces intense increase in the “D" layer ionization. Now due to increase in this “D" layer, it causes increased absorption of high frequency signals. Thus, it affects in [...]

Comparator is a circuit with two input terminals i.e. inverting and non-inverting. A standard voltage known as reference voltage Vref is connected to either inverting or non inverting terminal.
A mathematician named De Morgan developed a pair of important rules regarding group complementation in Boolean algebra. By group complementation, I’m referring to the complement of a group of terms, represented by a long bar over more than one variable.
Solve each question sincerely. You can check only one option, out of given four options. Once you submit your question paper, you will be prompted with either WRONG or CORRECT answers.
The oscillator is voltage controlled, so it is modulated by the audio signal that is applied to the base of Q2. R6 limits the input to the RF section, and it’s value can be adjusted as necessary to limit the volume of the input. L1 and C6 can be made with wire and a pencil.
How to get flicker-free fluorescent starting of fluorescent tube lights? Actually the fluorescent tubelights are now rarely used. But by chance, if you do have a one like this, then it is better for you to read this topic. Here there is an extremely simple but very effective modification which will eliminate the flickering when [...]
Resistor is an unavoidable element in electronics circuit. As we know there are different types of resistors. OK. This topic is not just to discuss the types of resistors in details. We are here to see some interesting practical tricks and tips with resistors. How to obtain an EXACT VALUE (I mean it!) of a [...]
Light Dependent Resistor – it is a passive light transducer. It is also called as photo-conductive cell because its conductivity changes due to change in light intensity. Basic Principle – when light falls on it its resistance decreases and when it is dark its resistance is maximum. The change in resistance is directly proportional to [...]
Detailed information about resistors… Resistor – the resistor is an element which opposes to the flow of electric current. Resistance is the property of the material by which it opposes to the flow of current, the current may be either AC or DC; it offers equal resistance to both. Basically their are two types of [...]
Refer the advanced version of this color code chart, with E series standard values of resistors. Resistors & Color Codes – the values of resistance of the resistor is indicated by four colored bands painted on the body of the resistor. These color bands can be translated into a number by using the following color [...]

This FM radio-controlled anti- theft alarm can be used with any vehicle having 6- to 12-volt DC supply system. The mini VHF, FM transmitter is fitted in the vehicle at night when it is parked in the car porch or car park. The receiver unit with CXA1019, a single IC-based FM radio module, which is [...]
For our ECE 4760 Final project we have developed a traction control system that detects wheel slip and adjusts the velocity of the wheels accordingly. Robotic vehicles are becoming increasingly complex and often need high levels of movement control. Specifically, when the wheels of a vehicle begin to slip, it is optimal to adjust their [...]
