In the given circuit find out the charge on each capacitor. (Initially they are uncharged)

Text Solution

Verified by Experts

Let potential at A is ` 0_1 ` so at D it is ` 30 V_1 ` at F it is 10 V and at point G potential is -25V . Now apply Kirchhoff's `I^(st) ` law at point E. ( total charge of all the plates ) connected to 'E' must be same as before i.e 0)
`therefore (x-10) +(x-30 ) 2+ (x+25) 2=0`
` 5x =4`
Final charges:

` Q_(1mu F) =( 10 -4 )= 6mu C `
` Q_( 2muF) = ( 4- ( -25) ) 2= 58mu C `
