A windshield wiper circuit is designed to use an RC charging circuit as a timer: whenever the capacitor reaches 50% full, the wiper blades are triggered, the capacitor is emptied, and the cycle repeats. Which of the following circuits would correspond to the fastest windshield wipers (that is, the most "wipes" per minute)? Vleilesents time scale A. A circuit with a 10-ohm resistor and a 150 mF capacitor B. A circuit with a 20-ohm resistor and a 100 mF capacitor of charging / ais (yal9ing C.
