Extracted text: Q1. In the adjacent figure each of the two capacitors mounted in parallel has a value C, the resistor has a value R, and the power supply has value ɛ = 25 V. Upon closing the key S the charging process of the two capacitors starts. The initial value of the electric current was Io = 25 mA, as shown in the table below, then the electric current decreased until it vanished at t = 00. The table below shows the values of the electric current every two seconds as measured by the ammeter A. t (s) 6 8 2 4 10 12 14 16 18 I (mA) q (mC) 25 20 16 13 10 7 4 40 55 66 75 89 97 a) Determine the value R of the resistor in kQ units. b) Plot the I-t graph (electric current versus time). c) Determine the circuit constant time t from the I-t graph. d) Determine the value C of each capacitor in µF units. e) Complete the table by evaluating the electric charge q(t) on each capacitor at the moments t = 2,12, 16, oo, ww
