Resistor, the most and crucial electronic component which is used in almost every electronic device. Even though our today’s discussion is on pull-up and pull-down resistors, the first and fundamental concept that we need to know is what is a resistor. So, a resistor is the two-terminal device which are used for the measurement of resistance. In the circuits, these resistors are used for the purpose of controlling current levels, voltage distribution, … [Read more...]

What is Ballistic Galvanometer : Construction & Its Working
The ballistic galvanometer is an instrument, which is used to measure or indicate current in a closed circuit. The galvanometer also is known as PMMC instrument, works on the principle of permanent magnet moving coil. The force is generated on the coil, due to Lorentz Force Law. Due to the interaction of fluxes, the pointer in the meter is deflected. Once the pointer is deflected, different torques are exerted on the pointer to make pointer stop at its … [Read more...]
What is a Discharge Lamp : Types & Their Working
In the initial period of 1856, discharge tubes came into existence, but discharge lamps existed in the market in the 1930s. Initially, a French scientist Jean Picard noticed that barren space in the mercury barometer shined as the mercury wiggled when he was carrying it. Many researchers along with Francis Hauksbee attempted to know the actual phenomenon behind it. Francis initially showed a discharge lamp in the year 1705. He demonstrated that either … [Read more...]

This IC was initially invented by Ernie Leroy Long in the year 1969 and the first application of this device was as a fuel injection system in the Ford car. There exist various models of LM386 … [Read more...]
What is Self Inductance : Theory, Examples & Applications
In the domain of electronics and electromagnetism industries, inductance is the movement of the electrical conductor to obstruct the flow of current. The current movement develops a magnetic field across the conductor and this field strength is based on the current magnitude and any current variations. From the principle of Faraday’s law of induction, any deviation in the magnetic field along the circuit generates an EMF voltage and this is termed as … [Read more...]
Know the Differences between DC Shunt Motor & DC Shunt Generator
In the scope of electrical technology, a parallel circuit is described to be shunt. Direct current motors and generators where the armature and field windings are parallelly connected are termed as DC shunt motors and DC shunt generators. Fundamentally, a similar machine can be utilized as motors and generators. The foremost variation in between these devices is that in the DC shunt motor the input is of electrical energy and the output is mechanical … [Read more...]
What is Permanent Magnet Stepper Motor : Working & Advantages
In the industrial domain progression, motors hold a very crucial role and their application is enhancing day-by-day. Not only in the power industries, but in many control applications, motors are playing a critical role. With the enhancement of motor control, the usage and implementation also augment every year. So, the stepper motor is a kind of control motor which operates on positioning control having no feedback loop. Stepper motors were formed at the … [Read more...]
What is a Multistage Amplifier : Design, Types & Its Applications
In many of the practical applications, the output of a single-stage amplifier is not sufficient to provide the required bandwidth or gain. So, the enhance either power or voltage gain, the multistage amplifier is required. These kinds of amplifier circuits hold the ability to offer augmented specifications and enhance the circuit performance and so preferred as fundamental building circuits for the development of complicated amplifier networks. This … [Read more...]
Difference between Resistance and Resistivity
In the electrical and electronics industries, the concepts of resistance and resistivity are the most important ones. One has to be clear regarding why these topics hold prominence and what are differences and comparison? The foremost difference is that resistance opposes the electron flow, while resistivity defines the material’s resistance having the corresponding dimension. So, here is a detailed view of all these topics. This article discusses an … [Read more...]
Differences between DC Series and Shunt Motors
Before knowing about the differences between DC Series and Shunt Motors, let us start to know what a DC motor is. An electric motor that is powered up by direct current is termed as DC motor. In a detailed view, when a current-carrying conductor is positioned in the area of a certain magnetic field, it gains some torque and tends to have a moment. So, this is the same principle where a DC motor also works on. A DC motor is also named depending on the type … [Read more...]
