Diode ratings – How to understand a diode datasheet?
Datasheets released by diode manufacturers contain a number of diode ratings. In order to select diodes for an application, it is important to understand all the ratings listed in the…
What is PIV rating in a diode?
PIV stands for 'Peak Inverse Voltage'. It refers to the maximum reverse bias voltage a semiconductor diode or other semiconductor devices can withstand without damaging themselves. The peak inverse voltage…
Hysteresis loss and Eddy current loss and their difference
In electric machines, a varying magnetic field causes eddy currents in all metallic parts and hysteresis in ferromagnetic core. The losses caused due to eddy currents are known as eddy…
Zener diodes – Operation, Symbol and V-I Characteristics
What are zener diodes? Zener diodes are silicon semiconductor devices that can allow the passage of current in both forward and reverse directions. Unlike p-n junction diodes, they are designed…
Difference between resistance and impedance
When we speak about DC electricity, resistance is the term used to refer to opposition to current flow whereas impedance is the term used in AC electricity. Impedance is basically…
Difference between EMF and Voltage
The difference between EMF and voltage is that the EMF is the potential difference measured across a power source without a load connected to it whereas voltage is the potential…
Differences between resistance and resistivity
Understanding the differences between resistance and resistivity is very important as they are closely related. This article aims to bring you clarity on resistance and resistivity by comparing each of…
What is induced current?
Electromagnetic induction occurs whenever there is a relative motion between a magnetic field and a coil. The electromagnetic force acts on the charged particles inside the coil, forcing them in…
Electromagnetic Induction
Electromagnetic induction is a phenomenon by which electromotive force is produced across a conductor placed in a varying magnetic field. It was discovered by Michael Faraday in 1831 after performing…
