Question

According to its design specification, the timer circuit delaying the closing of an elevator door is to have a capacitance of 35.0 μF 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 38.6 μΕ 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 38.6 μF capacitor? In serles in parallel (b) What should be its capacitance? (c) The next circuit comes down the assembly line with capacitance 34.1 HF between A and 8. To meet the specification, what additional capacitor should be installed in series or in parallel in that circuit? magnitude orientatin Select-

Answer 1

a) it should be in series

with value b) 375.28 micro Farad

c) it should be connected in series to have lower capacitance

value , 292.502 micro Farad

please rate it up thanks :)
