Q53

If the current through an electrical machine running on direct current is 15 A15\text{ A} and the machine runs for 10 minutes10\text{ minutes}, the charge that passes through the machine during this time is :

  1. (a) 1.50 C1.50\text{ C}
  2. (b) 150 C150\text{ C}
  3. (c) 900 C900\text{ C}
  4. (d) 9000 C9000\text{ C}Correct answer

Solution.

Answer: (d) 9000 C9000\text{ C}

  1. Charge Q = It.
  2. Convert 10 minutes to 600 seconds, then Q = 15 × 600 = 9000 coulombs.
