JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
Figure shows charge \((q)\) versus voltage \((V)\) graph for series and parallel combination of to given capacitors. The capacitances are
- A \(40\,\mu F\) and \(10\, \mu F\)
- B \(50\,\mu F\) and \(30\, \mu F\)
- C \(60\,\mu F\) and \(40\, \mu F\)
- D \(20\,\mu F\) and \(30\, \mu F\)
Answer & Solution
Correct Answer
(A) \(40\,\mu F\) and \(10\, \mu F\)
Step-by-step Solution
Detailed explanation
As \(q=C V\) Hence slope of graph will give capacitance. Slope will be more in parallel combination. Hence capacitance in parallel should be \(50\, \mu \mathrm{F}\) and in series combination must be \(8\, \mu F\). Only in option \(40\, \mu F\) and \(10\, \mu \mathrm{F}\).…
