Given C1 + C2 = 16 mu F (Equation 1)

Here are the solutions to the problems:

a) Capacitors
Let the capacitances of the two capacitors be $C_1$ and $C_2$.

• When connected in parallel, the effective capacitance is $C_1 + C_2$. Given $C_1 + C_2 = 16 \mu F$ (Equation 1)

• When connected in series, the effective capacitance is $\frac{C_1 C_2}{C_1 + C_2}$. Given $\frac{C_1 C_2}{C_1 + C_2} = 3 \mu F$ (Equation 2)

Substitute Equation 1 into Equation 2:
