Exercises:

1. Use the relation for a parallel plate capacitor C proportional to A/d A is the area of a single plate and d is the distance between the plates. Also use the relation C = Q/V or Q= CV. Then you can see in this C is the slope of the graph of Q(V) vs V. The larger the value of C the steeper the slope of this graph. Then for the correlation 1=b, 2=a, and 3=c.

2. To determine if a capacitor is in parallel look to see if the wires attaching can be removed and replaced with a single wire and twice the capacitive area. Are the wires common to a junction point and if so the capacitors are in parallel. Configuration a is a series, configuration b is in parallel, and configuration c) is a combination.

3. The configuration is a set of 3 capacitors in series . The potential difference for the series combination is Vbattery = V1 + V2 + V3 but here each ...
