After how much time capacitor is considered as fully charged:
(A) three time constants (3T)
(B) four time constants (4T)
(C) five time constants (5T)
(D) None of these
Answer: (C) five time constants (5T)
After five time constants (5T) it reaches 99.3% charge, so at this point the capacitor is considered to be fully charged.
