Three capacitors are in parallel with values of C1=0.15, C2=0.20, and C3=0.30. What is the total capacitance?

When capacitors are connected in parallel, the total capacitance is calculated by simply summing the capacitances of each individual capacitor. This is due to the fact that in a parallel circuit, the voltage across each capacitor is the same, and therefore, the total charge stored is the sum of the charges stored in each capacitor.

For the given capacitors, the values are:

• C1 = 0.15 microfarads

• C2 = 0.20 microfarads

• C3 = 0.30 microfarads

To find the total capacitance (C_total), you add these values together:

C_total = C1 + C2 + C3

C_total = 0.15 + 0.20 + 0.30

C_total = 0.65 microfarads

Thus, the total capacitance of the three capacitors in parallel is 0.65 microfarads. This aligns perfectly with the provided answer option, confirming its correctness. It is important to remember that this method of summation applies only when capacitors are connected in parallel.
