25. Suppose 1018 electrons start at rest and move along a wire through a +12-V potential difference. (a) Calculate the change in electrical potential energy of all the electrons. (b) The final speed of the electrons is 0.10 m/s. Use the work-energy equation to cal- culate the increase in thermal energy in the wire due to collisions of the electrons with atoms in the wire. The mass of an electron is 811 Y 10-31 kg.
