Question 3 E ww Figure 2 (a) Two capacitors C, and C; and two resistors are connected to a battery in an arrangement as shown in Figure 2. Given that, R is 100 2 and C, = C;=500 µF, caleulate the time constant for the circuit. After fully charged, the capacitors are disconnected from the battery, E. Calculate the time taken for total energy stored and charge in the two capacitors to become half of the initial value.

Example1: a) A battery has internal resistance r = 0.005 N when it is new. The internal resistance increases to r = 2.0 N when the battery gets old. What happens to the voltage of the ideal battery, ɛ ? Circle one. a Increase I decrease I stays the same Fig A b) What happens to the terminal voltage Vab between points a and b as the battery gets older. Increase I decrease | stays the same
