Chapter 26.2, Problem 26.2QQ
Many computer keyboard buttons are constructed of capacitors as shown in Figure 25.3. When a key is pushed down, the soft insulator between the movable plate and the fixed plate is compressed. When the key is pressed, what happens to the capacitance? (a) It increases. (b) It decreases. (c) It changes in a way you cannot determine because the electric circuit connected to the keyboard button may cause a change in ΔV.
