1. At a typical drift speed of 5*10^-5 m/s, it takes an electron about 100 minutes to travel through one of your connecting wires. Why then does the bulb light immediately when the connecting wire is attached to the battery?

2 a) The emf of a particular flashlight battery is 1.7 volts. If the battery is 4.5 cm long and the radius of the cylindrical battery is 1 cm, estimate roughly the amount of charge on the positive end plate of the battery.

b) Is this amount of charge sufficient to repel noticeably a positively charged piece of invisible tape?
