Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.

First law of thermodynamics is stand on the principle of the conservation of power. According to the first law, ΔQ = W + ΔU Where, Δ Q = heat given to the system
Vgs= -1.5 v Idss= 10 mA Vp = - 4 v Ids = ? Vds = ?
Q. What is a power? Answer: That seat of EMF" reply is SO wrong. Not merely is the rate of charge delivery not power but a seat of EMF doesn't deliver charge. A seat of EM
