Question

Question 5 1 pts Two identical capacitors (each of capacitance C) in series are connected to the battery. The third capacitor of capacitance 2C at some moment is connected in parallel to the first two. Adding this third capacitor will keep the charge on first two the same will increase charge on first two capacitors somehow change the charge on the first two capacitors, but impossible to predict how. will decrase charge on first two capacitors

Answer 1

charge across a capacitor C_1. F, connected to a battery of V_1 volts, is given by Q = C_1V_1. As the capacitor with capacitance 2C is connected in parallel across the sourec (emf = v) (as shown in fig. 1) The total voltage across each capacitor C does not change and hence the charge on the first two remains the same rightdoublearrow option (i) is the correct choice
