Answer to Question #26216 in Electricity and Magnetism for jennifer

Question

According to its design specification, the timer circuit
delaying the closing of an elevator door is to have a capacitance of 32.0 ohmF between two points A and B. When
one circuit is being constructed, the inexpensive but
durable capacitor installed between these two points is
found to have capacitance 34.8 %F. To meet the specification, one additional capacitor can be placed between the
two points. (a) Should it be in series or in parallel with the
34.8-%F capacitor? (b) What should be its capacitance?
(c) What If? The next circuit comes down the assembly line with capacitance 29.8 %F between A and B. to meet the specification, what additional capacitor should be installed in series or in parallel in that circuit?
