MHT CET · Physics · Capacitance
The equivalent capacitance between points \(\mathrm{A}\) and \(\mathrm{B}\) as shown in figure is
- A \(\frac{4}{3} C\)
- B \(2 C\)
- C \(5 C\)
- D \(\frac{3}{2} C\)
Answer & Solution
Correct Answer
(B) \(2 C\)
Step-by-step Solution
Detailed explanation
Equivalent circuit, uing potential at \(\mathrm{P}\) is same as at \(\mathrm{A}\) and potential at \(R\) is same as at \(B\).
This is equivalent to following:
Therefore, the equivalent capacitance across AB is given by,
\(\Rightarrow C_{A B}=C+\frac{C}{2}+\frac{C}{2}=2 C\)
This is equivalent to following:
Therefore, the equivalent capacitance across AB is given by,
\(\Rightarrow C_{A B}=C+\frac{C}{2}+\frac{C}{2}=2 C\)
