Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of

Three inductive loads, each of resistance 4Ω and reactance 9Ω are linked in delta. When linked to a 3-phase supply the loads consume 1.2kW. Calculate (a) The power factor of
how much power is radiated by a tungsten sphere of radius 16cm at a temperature of 25 degrees Celsius emissivity is 0.35
MANUFACTURING: The resistance element is used as a wire, made from special alloys, which have small low temperature coefficient and good stability against environmental c
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
