Electrons flow very slowly through a circuit, yet it does not take a noticeably long time for a lamp to light up when you turn on a distant switch. How quickly a lamp lights up after an electrical switch is closed does not depend on the drift velocity of the conduction electrons, but depends on the speed at which the propagates through the circuit, which is about the speed of light.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
