Figure. shows two concentric coplanar coils with radii a and b(alt ltb) . A current I = 2t flows in the smaller loop. Neglecting self-inductance of the larger loop, if a capacitor of capacitance C is also connected in the larger loop as shows in Fig . , find the charge on the capacitor as a function of time.

Two concentric and coplanar coils have radii a and b ( gt gt a) as shows in Fig. Resistance of the inner coil is R . Current in the outer coil is increased from 0 to i , then the total charge circulating the inner coil is

find of the An archery target has three regions formed by three concentric circles as shown in Fig 15.8. If the diameters of the concentric circles are in the ratio 1:2:3 . , then find the ratio of the areas of three regions Fig. 15.8

There are two coils A and B as shown in Fig.

There are two coils A and B as shown in Fig.

An otherwise infinite, straight wire has two concentric loops of radii a and b carrying equal currents in opposite directions as shown in Fig. The magnetic field at the common centre is zero for
