Rotary Variable Differential Transformer-RVDT

Principle of RVDT:
RVDT is used where precise angular movement is to be measured. RVDT uses the same principle as the LVDT except that, LVDT is for linear measurement while RVDT is for Angular one.
Construction and Working of RVDT:
RVDT is almost identical in the construction with LVDT. The ferrite core in LVDT is replaced by heart [...]

Electronics

Linear Variable Differential Transformer-LVDT

What is LVDT?
The major use of LVDT is to convert the Rectilinear Physical Motion into Equivalent electrical signal. So LVDT is the sort of transducer which, by means of change in the electrical field of charged coil, changes the output and this change in the output is used to measure the displacement of the object.
Construction [...]

Electromagnetic Bomb

Introduction to E-Bomb:
An e-bomb (electromagnetic bomb) is a weapon that uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. At low levels, the pulse temporarily disables electronics systems; mid-range levels corrupt computer data. Very high levels completely destroy electronic circuitry, thus disabling any [...]
