Concepts Of Physics MCQ Edition [Volume 2]PhysicsCapacitors
Determine the equivalent capacitance of the combination depicted in the figure.
Options
- AC
- BC/2
- C3C
- D2C
Correct answer
D. 2C
Step-by-step solution
Let the left terminal be node A and the right terminal be node B . The left plates of the top and bottom capacitors are directly connected to node A . The right plates of the top and bottom capacitors are connected to the top and bottom wires, respectively. These wires are joined together at the right end by a vertical wire and connected to node B . Thus, the right plates of both these capacitors are at the potential of node B . The middle capacitor is connected between the top and bottom wires. Since both these wi
