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 lo = 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 R current every two seconds as measured by the ammeter A. t(s)02|4| 6 8 | 10 12 14 16 18 0 I (mA) 25 20 16 13 10 8 75 4 3 0 9 (mC) 40 55 66 75 89 97 a) Determine the value R of the resistor in kN units.
