Question

A bulb in a table lamp has a current of 0.20 A through it. Part A. Determine the rate of the number of electrons passing through the wire leading to the bulb. Part B. Determine the number of electrons leading to the bulb in one minute. A bulb in a table lamp has a current of 0.20 A through it. Part A. Determine the rate of the number of electrons passing through the wire leading to the bulb. Part B. Determine the number of electrons leading to the bulb in one minute. Part A. Determine the rate of the number of electrons passing through the wire leading to the bulb. Part B. Determine the number of electrons leading to the bulb in one minute.

Explanation / Answer

a) I=Q/t= ne/t

==> n/t =I/e=0.2/(1.6E-19)= 1.25 E18 Electrons /second

b) in one minute = 1.25 E18*60 = 7.5 E19 electrones
