(a) State the postulate of STR and deduce Lorentz Transformation.
OR
Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations.
(b) Prove that particle having rest mass zero is always moving with velocity of light.
A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V. The secondary winding gives a full load current of 30A at a power factor of 0.8 l
