The diagram shows four capacitors with capacitances and break down voltages as mentioned. What should be the maximum value of the external emf source such that no capavitor breaks down?[Hint: First of all find out the break down voltages of each branch. After that compare them.]
(A) \( 2.5 \mathrm{kV} \)
(B) \( 10 / 3 \mathrm{kV} \)
(C) \( 3 \mathrm{kV} \)
(D) \( 1 \mathrm{kV} \)
