pi filter Operation
The below Fig shows a typical capacitor input filter or Ï€- filter. It consists of a filter capacitor C1 connected across the rectifier output, a choke L in series and another…
Choke Input Filter Operation
The below Fig. shows a typical choke input filter circuit.  It consists of a Choke L connected in series with the rectifier output and a filter capacitor C across the load.…
Capacitor Filter Operation
Capacitor filter.  Fig. shows a typical capacitor filter circuit.  It consists of a capacitor C placed across the rectifier output in parallel with load RL. The pulsating direct voltage of the…
What is a Filter Circuit ?
Generally, a rectifier is required to produce pure d.c. supply for using at various places in the electronic circuits. However, the output of a rectifier has pulsating character i.e. it…
Laser Level Measurement Principle
The least-common form of echo-based level measurement is laser, which uses pulses of laser light reflected off the surface of a liquid to detect the liquid level. Perhaps the most…
Argonite Fire Suppression System Working Principle
Argonite is a composite gas that consists of 50% Nitrogen and 50% Argon. The gas is mixed and stored under pressure. The composite is completely inactive and is not involved…
Transistor as Amplifier
A transistor raises the strength of a weak signal and thus acts as an amplifier. The Below Fig shows the basic circuit of a transistor amplifier. The weak signal is applied between emitter-base junction…
Selection Guidelines for Cable Glands
There are many factors to consider when selecting cable glands for industrial installations. Neglecting to pay due attention to some of these factors may cause unnecessary anxiety at a future…
Token Ring and Token Bus Working Animation
Token Ring At the start, a free Token is circulating on the ring, this is a data frame which to all intents and purposes is an empty vessel for transporting…
Working of NPN Transistor
The emitter-base junction of a transistor is forward biased whereas collector-base junction is reverse biased. If for a moment, we ignore the presence of emitter-base junction, then practically (Note 1) no current…
