Older ballasts with an iron core are basically an autotransformer. They transform voltage to a higher voltage with a single winding. Electronic Transformers increase voltage with capacitors and diodes.
The principles of operation of the automatic voltage regulator is that of the excitation system. The working principle is to regulate the flow of reinforcement on the exciter.
They usually respond to airborne volatile chemicals, which are typical around explosives.
The end sockets have to be rewired. The schematic for the rewire is on the ballast label.
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
principle refers to the basic objective of something. Operation refers to how it operates.
Yes, an electrical timer can be used to control the on and off operation of the power to self ballast lamps.
Give a brief idea of principle of hysteresis motor,application.
Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)

The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.
The principle of operation involves using a fan mounted in the top of the cabinet to draw a curtain of sterile air over the products that are being handled.
The principle that concentrates the effects is called the Mass Principle of War. It concentrates the effects of combat power for the best results.
