Question
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 = o. The table below shows the values of the electric
R:
current every two seconds as measured by the ammeter A.
