Find charge on 12 nF which is in direct contact to battery (initially all capacitors are uncharged)
Find charge on 12 nF which is in direct contact to battery (initially all capacitors are uncharged)
Open in App
Solution
The correct option is A 160 nC
The given circuit is reduced to the circuits as shown above.
Wheatstone bridges with 5 nF & 18 nF do not get any charge. Now calculating the effective capacitance of the rest of the capacitors we get,
Ceff across battery is 40 nF.
q=CeffV=160 nC
