The capacitor C3 of the circuit in the figure below, on the left, is a capacitor whose capacitance can be varied. O
graph in the figure below, on the right, represents the electric potential V1 between the plates of the capacitor
C1 as a function of C3. For different values of C3 we have different values for
V1. We know that the electric potential V1 tends asymptotically to 10 volts when
C3 → ∞.
Determine:
a) The electric potential V of the source;
b) The values of C1 and C2.
