If the conductor in the above question (i.e., Q.1) is a 20 feet long wire in your automobile, approximately how long would it take an electron to travel from the negative terminal to the positive terminal of the battery?
A
1 second
B
2 hours
C
1 week
D
6 days
Answer
1 week
Explanation
Solution
The time taken for an electron to travel a certain distance at a constant drift velocity is given by t=vdL. Assuming the drift velocity is approximately 10−5 m/s and the length is 20 feet (approximately 6 meters), the travel time is of the order of weeks. Based on the provided options and the likely intended answer, the time is approximately 1 week.
