Find the charging and discharging time of 0.5µF capacitor.
A. Charging time=2ms; Discharging time=5ms.
B. Charging time=5ms; Discharging time=2ms.
C. Charging time=3ms; Discharging time=5ms.
D. Charging time=5ms; Discharging time=3ms.
Answer:A
Find the charging and discharging time of 0.5µF capacitor.
A. Charging time=2ms; Discharging time=5ms. B. Charging time=5ms; Discharging time=2ms. C. Charging time=3ms; Discharging time=5ms. D. Charging time=5ms; Discharging time=3ms.
Explanation: The time required to charge the capacitor is tHigh=0.69(RA+RB)C =0.69(10kΩ+5kΩ)x0.5µF =5ms.
