Timing and Wave Shaping capacitor applications are the next type to examine. Recalling the decoupling analogy of the water system, the presentation will focus on the time involved in filling the water tank and dumping it into the sink. For example, if there is a bucket and it is being filled with water, the size of the garden hose would make a difference in how fast the bucket got filled. A larger hose would fill the bucket faster than a smaller hose. This same concept can be applied to electronic circuits where the capacitor is charged and discharged at different rates. An engineer designing a timing circuit is careful to choose a capacitor based on how quickly it can be filled, dumped and refilled. In the example of the intermittent windshield wipers, the longer the delay the smaller the rate of energy that is being transferred to the capacitor. The shorter the delay the faster the capacitor is being charged and discharged. Note that it is also possible to keep the charge rate constant but change the size of the capacitor, larger capacitors will take longer to charge up than smaller capacitors.
