Multimeter A multimeter is a PMMC meter. To measure DC current the meter acts as an ammeter with a low series resistance. Range changing is accomplished by shunts in such a way that the current passing through the meter does not exceed the maximum rated value. A multimeter consists of an ammeter, voltmeter, and ohmmeter […]
Power Supply Power is the backbone of any electronic system and the power supply is what feeds the system. Choosing the right supply can be the critical difference between a device working at optimum levels and one that may deliver inconsistent results. In addition to alternating current (AC) to direct current (DC) power supplies, DC-to-DC
What is CRO In electronics, CRO typically stands for “Cathode Ray Oscilloscope.” A Cathode Ray Oscilloscope is a type of electronic test instrument that allows for the visual representation of electrical signals. Difference between CRO and DSO

Introduction to MATLAB Programming Accessing MATLAB MATLAB can be assessed through various modes. Basics: Variables and Operators Operators in MATLAB: 1 Add a+b 2 Subtract a-b 3 Multiply a*b 4 Divide a/b 5 Exponent a^b 1 Greater than > 2 Less than < 3 Greater than or equal to >= 4 Less than or equal
Cathode Ray Oscilloscope/ Digital Storage Oscilloscope An oscilloscope is a test instrument which allows us to look at the ‘shape’ of electrical, signals by displaying a graph of voltage against time on its screen. It is like a voltmeter with the valuable extra function of showing how the voltage varies with time. A graticule with
Superposition Theorem The superposition principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or currents through) that element due to each independent source acting alone. The strategy used in the superposition theorem is to eliminate all the independent sources except one
Function generator Function Generator is basically a signal generator that produces different types of waveforms at the output. It has the ability to produce waveforms such as sine wave, square wave, a triangular wave, sawtooth wave etc. An adjustable frequency range is provided by the function generator which is in the range of some Hz

Breadboard Breadboards as shown in Figure…. are one of the most fundamental pieces when learning how to build circuits. These “solder-less” breadboards [1] are great units for making temporary circuits and prototyping, and they require absolutely no soldering [2]. Another common use of breadboards is testing out new parts, such as Integrated circuits (ICs). The
The Inductor, also called a choke, is another passive type electrical component designed to take advantage of the principle that a current carrying coil has a magnetic flux developed across it, whose magnitude is directly proportional to the amount of current, (direction given by Fleming’s Left Hand rule). It induces a voltage into the coil
Capacitor The Capacitor, also known as a Condenser, is also a passive component just like a resistance. It stores its energy in the form of an electrostatic field producing a potential difference (static voltage) across its plates. It consists of two conductive plates which are not connected but are electrically separated by an insulating material
