Q: The current of 0.9A is drawn by a filament of an electric bulb for two minutes. The charge flowing through the circuit is ?
  • A. 1.08 C
  • B. 10.8 C
  • C. 108 C
  • D. 1.8 C
Correct Answer: Option C - Given- Electric current (I) = 0.9 A, t = 2 minutes, = 120 sec. (Q) = ? Electric current = charge / time Q = I x t = 0.9 x 2 x 60 = 0.9 x 120 = 108 coulomb
C. Given- Electric current (I) = 0.9 A, t = 2 minutes, = 120 sec. (Q) = ? Electric current = charge / time Q = I x t = 0.9 x 2 x 60 = 0.9 x 120 = 108 coulomb
