The liquids which permits the current to pass by them and also dissociates into ions on passing current by them are named electrolytes e.g. resolution of salts, bases and acids in water, etc.
Those liquids which do not permit current to pass by them are known as insulators (e.g. vegetable oils, distilled water etc.)
Olbers' paradox (H. Olbers; 1826): If the Universe is uniform, infinite & unchanging then the whole sky at night would be bright regarding as bright as the Sun. The further yo
Q. Tritium has a half life period of 12.5 years. What fraction of the sample will be left over after 25 years? HLP = 12.5 years Number of HLPs in 25 years = 25 / 12.5 =2

The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
