Inrush current is the maximum current drawn by an electrical circuit at the time it’s turned ON. It appears for the few cycles of input waveform. The value of the inrush current is much higher than the steady-state current of the circuit and this high current can damage the device or trigger the circuit breaker. Inrush Current generally appears in all the devices where…
MOSFET is basically a transistor which uses field effect. MOSFET stands for Metal Oxide Field Effect Transistor, which has a gate. The gate voltage determines the conductivity of the device. Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like we use Transistor as a switch or as an amplifier.

In the previous tutorial, we have learned about OpenCV and done some basic image processing using it like grey scaling, color saturation, histogram, color spaces, RGB component etc. As told in the previous tutorial, OpenCV is Open Source Commuter Vision Library which has C++, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. So it can be…
IoT is everywhere. Working hand in hand with technologies like blockchain and machine learning, it is changing everything, from the way we order groceries, to the way we maintain machines and equipment. The applications of IoT cuts across all fields and industries. From utility management and transportation to education and agriculture, helping businesses to deliver more…
To turn on a Thyristor, there are various triggering methods in which a trigger pulse is applied at its Gate terminal. Similarly, there are various techniques to turn off a Thyristor; these techniques are called Thyristor Commutation Techniques. It can be done by bringing the Thyristor back into the forward blocking state from the forward conduction state. To bring the…
Art is a way of seeing, and they say seeing is believing, but the opposite is also true, believing is seeing and it’s really hard to imagine living in this world without the gift of vision – our eyes, how wonderful it is being an infant when our eyes just open we see the world and started to recognize and see the world around us but as the time passes by, the same wonderful…
Software development is generally difficult but for an embedded system, it’s on a whole new level of difficulty. Firmware developers need to have good knowledge about hardware development and understand the internal workings of an embedded processor. For today's Article, I will be sharing tools and tips that could be used to achieve a high level of efficiency and eliminate…
Almost every portable and handheld device consists of a battery. The battery is a storage device where energy is stored to provide power whenever needed. There are different types of batteries available in this modern electronics world, among them Lead Acid battery is commonly used for high power supply. Usually Lead Acid batteries are bigger in size with hard and heavy…
Power inverters are fundamental devices for power electronics that convert DC (Direct Current) into AC (Alternating Current). There are many types of power inverters specific for use in residential, commercial, and industrial systems. It is important to understand the types of power inverters in power electronics to make the appropriate decision about the type of power inverter you would like…
In electronics, Amplifier is the most commonly used circuit device with huge application possibilities. In Audio related electronics pre-amplifier and power amplifiers are two different types of amplifier systems which are used for sound amplification related purposes. But, other than this application-specific purpose, there are huge differences in various types of…
On 7th January 2013, a Boeing 787 flight was parked for maintenance, during that a mechanic noticed flames and smoke coming from the Auxiliary power unit (Lithium battery Pack) of the flight, which is used to power the electronic flight systems. Efforts were taken to put the fire off, but 10 days later before this issue could be resolved, on 16th January another battery…
Resistors are current limiting devices with are used abundantly in electronics circuits and products. It is a passive component which provides resistance when current flow through it. There are many different types of resistors. Resistance is measured in Ohm with a sign of Ω.
What are Pull-up and Pull-Down…
