1. A capacitor with plates 7.5 cm x 8 cm and plate separation of 0.1 mm has an oil dielectric:

a. Compute its capacitance;

b. If the charge on this capacitor is 0.424 µC, what is the voltage across its plates?

2. For a parallel-plate capacitor, if you triple the plate area and halve the plate spacing, how does capacitance change?

3. For the capacitor of Figure 10–6, if you use mica instead of ceramic, what will be the capacitance?

4. What is the dielectric for the capacitor of Figure 10–7(b)?
