The dimension of combination (L)/(CVR) are same as dimensions of :-
It is desired to make an achromatic combination of two lenses, (L_(1)& L_(2)) made of materials having dispersive power omega_(1) and omega_(2)(ltomega_(1)) . If the combination of lenses is converging then:
Two series resonant circuits with component values L_(1) C_(1) and L_(2) C_(2) , respectively have the same resonant frequency, They are then connected in series, so that the combination has the same resonant frequency
In Fig. coil 1 and coil 2 are wound on a long cylindrical insulator. The ends A' and B are joined together and current I is passed. Self-inductance of the two coils are L_(1) and L_(2) , and their mutual inductance is M . a. Show that this combination can be replaced by a single coil of equivalent inductange given by L_(eq) = L_(1) + L_(2) + 2M . b. How could the coils be reconnected by yieldings an equivalent inductance of L_(eq) = L_(1) + L_(2) - 2M .

Two wires of equal diameters, of resistivities rho_(1) and rho_(2) and length l_(1) and l_(2) , respectively of the combination is
There are two rods of length l_1 l_2 and coefficient of linear expansions are alpha_1 and alpha_2 respectively. Find equivalent coefficient of thermal expansion for their combination in series.
