Problem 2 Suppose that we have two capacitors, C₁ = 100 μF and C2 = 50 μF. Capacitor C₁ is charged to an initial voltage of 40 V, and capacitor C₂ is charged to 75 V. If they are placed in series with the negative terminal of capacitor C₁ to the positive terminal of capacitor C2, determine the equivalent capacitance, its initial voltage, and the charge stored on the two capacitors. Compute the total energy stored in the equivalent capacitance.

Problem 2
Suppose that we have two capacitors, C1 = 100 μF and C₂ = 50 μF. Capacitor C1 is charged to an
initial voltage of 40 V, and capacitor C₂ is charged to 75 V. If they are placed in series with the
negative terminal of capacitor C₁ to the positive terminal of capacitor C₂, determine the
equivalent capacitance, its initial voltage, and the charge stored on the two capacitors.
Compute the total energy stored in the equivalent capacitance.
