Question

Figure 21 displays two capacitors in a parallel arrangement. One capacitor is 1 µF (C1) and the other capacitor is 3 µF (C2). Calculate the total capacitance of the circuit.

Options:

0.25 µF
1.5 µF
4 µF
12 µF

Answer 1

The total capacitance of a 1 µF capacitor and a 3 µF capacitor in parallel is 4 µF.

Step-by-step explanation:

To calculate the total capacitance of two capacitors in a parallel arrangement, we simply add their values together. Given that one capacitor (C1) is 1 µF and the other (C2) is 3 µF, the total capacitance (Ct) can be found using the formula Ct = C1 + C2.

So, Ct = 1 µF + 3 µF = 4 µF. This is the total capacitance of the circuit when two capacitors are placed in parallel.
