9. In the given figure, the equivalent capacitancebetween A and Bis 5 uF. Calculate capacitance C.2uFАо--11 uF4 uF4FOB

Answer»

For upper branch net capacitance is 1uC. Given net capacitance is 5, so bottom branch should have capacitance 4(because in case of parallel capacitors they are added directly).now in bottom branch you are getting two capacitors one of 8( net of two 4 capacitors) other of unknown value C. so Capacitor C have value 8(in case of series capacitors they are added in inverse).So final answer is 8.
