An electrical system connected to a 98 V voltage source (without
internal resistance), works with a compound RC circuit with a
resistance of R = 9 Ω and two capacitors (initially discharged)
with equal capacitances of C1 = C2 = 5 μF, thus as a switch that is
connected to terminal a to carry out the charging process on the
capacitors, until a very long time passes, in such a way that in
the end the capacitors are fully charged....
