You are provided with three capacitors with capacitance 4F, 3F, 2F, respectively.

What is the maximum capacitance which can be obtained by connecting the three capacitors? [3marks]

1 answer

To obtain the maximum capacitance, we should connect the capacitors in parallel. When capacitors are connected in parallel, the total capacitance \( C_{total} \) is the sum of the individual capacitances:

\[ C_{total} = C_1 + C_2 + C_3 \]

Given the capacitances:

  • \( C_1 = 4F \)
  • \( C_2 = 3F \)
  • \( C_3 = 2F \)

Now, we can calculate the total capacitance:

\[ C_{total} = 4F + 3F + 2F = 9F \]

Thus, the maximum capacitance that can be obtained by connecting the three capacitors is 9 Farads.
