Answer / nahin

yes.
fluorescent bulb works under the principle of scattering of
electron.An incident electron collides with an atom in the
gas. According to the Einstein formula: Kmax=hf+phi,
the kinetic energy depends on the frequency. So, if we
reduce the frequency, the kinetic energy of electrons will
also be reduced and thus the performance will be degraded.

flurescent lamp in 50hz supply 20milli second one time
reached in zero position in sine wave (that time light not
glowing) that time is very less. in 25hz supply 40ms one
time reached in zero position that time light not full
brightness compared to 50hz supply.

A three phase load, around 4 km away from the 11/0.433KV distribution transformer (Neutral of Transformer is solidily earthed) and consisting of mainly very costly and sensitive electronic equipments is giving trouble due to high voltage difference between neutral and body earth. Whether this problem can addressed by connecting neutral at the load point solidly to earth?

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
