Chapter 25: Q7Q (page 739)

For each circuit in Fig. 25-21, are the capacitors connected in series, in parallel, or in neither mode?

Short Answer

Expert verified
  1. The capacitors in figure (a) are in series
  2. Thecapacitors in figure (b) are in parallel
  3. The capacitors in figure (c) are in parallel.

Step by step solution

01

The given data

Figure 25-21 is given.

02

Understanding the concept of the capacitor connection

Analyzing circuits given in Fig.25-21, we can note whether the current is dividing or not in it. From this, we can predict whether the capacitors are connected in series, in parallel, or neither mode.

03

Calculation for predicting the capacitors connection

In Fig. 25-21(a), we can see that there is only one path of current and the current is not dividing.

Therefore, the capacitors in figure (a) are in series.

In Fig. 25-21(b) and (c), we can see that, the current is dividing intol1 and l2.

Therefore, the capacitors in figures (b) and (c) are in parallel.
