Capacitors - Technical MCQs
Q1:
 How long would it take the capacitor in the given circuit to completely charge if the switch was in position 1?A 22 ms
B 69 ms
C 345 ms
D 440 ms
ANS:C - 345 ms T= rc = (4.7 +2.2) *10 ^3 ohms * (10* 10^-6 Farad) = 69 mill sec But the time required for capacitor to fully charge is 5T. So 5*69 milli sec= 345 mSec. Share : |
