Four capacitor each of capacitance 16μF are connected as shown in the figure. The capacitance between points A and B is : ______ (in μF).
Answer: 64
Solution
Tracing the connections, the top rail forms one common node joined to terminal B, while the lower junctions form the other common node joined to terminal A. Each of the four capacitors is connected directly across these same two nodes, so all four are in parallel. The equivalent capacitance is
