MHT CET · Physics · Capacitance
The graph shows the variation of voltage ' V ' across the plates of two capacitors \(A\) and \(B\) versus increase in charge ' \(Q\) ' stored in them. Then
- A capacitance A has high capacity.
- B capacitance B has high capacity.
- C both have same capacity.
- D capacity of \(\mathrm{A}=2\) times capacity of B .
Answer & Solution
Correct Answer
(A) capacitance A has high capacity.
Step-by-step Solution
Detailed explanation
\(\mathrm{Q}=\mathrm{CV}\)
Comparing it with \(\mathrm{y}=\mathrm{mx}\),
\(\therefore \frac{\mathrm{Q}}{\mathrm{~V}}=\mathrm{C}=\frac{1}{\text { slope of line }}\)
As slope of A is smaller than B, the capacitance of A is greater than B .
