TS EAMCET · Physics · Capacitance
Two capacitors of capacitances \(1 \mu \mathrm{~F}\) and \(2 \mu \mathrm{~F}\) can separately withstand potentials of 6 kV and 4 kV respectively. The total potential, they together can withstand when they are connected in series is
- A 9 kV
- B 4 kV
- C 6 kV
- D 2 kV
Answer & Solution
Correct Answer
(A) 9 kV
Step-by-step Solution
Detailed explanation
\begin{aligned} & \quad \mathrm{C}_1=1 \mu \mathrm{~F}, \mathrm{C}_2=2 \mu \mathrm{~F}, \mathrm{~V}_1=6 \mathrm{kV}, \mathrm{V}_2=4 \mathrm{kV} \\ & \therefore \quad \mathrm{Q}_1=\mathrm{C}_1 \mathrm{~V}_1=1 \times 10^{-6} \times 6 \times 10^3=6 \times 10^{-3} \mathrm{C} \\ &…
