A flow of 107 electrons per second in a conductor constitutes a current of:

Correct answer: C. 1.6 x 10^-12 A

  • A. 1.6 x 10^-26 A
  • B. 1.6 x 10^12 A
  • C. 1.6 x 10^-12 A
  • D. 107 A

Explanation

This option correctly states that the current flowing through the conductor is 1.6×10−12 amperes. This value was obtained by calculating the total charge passing through the conductor per second using the formula I=Q/t , where Q is the charge and t is the time. Therefore, option C is correct.

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
