In the figure below, a battery of potential difference V = 38 V is connected to a resistive strip of resistance R = 8.0 Ω. When an electron moves through the strip from one end to the other, (a) in which direction in the figure does the electron move (1 = upward, 2 = downward), (b) how much work (in eV) is done on the electron by the electric field in the strip, and (c) how much energy (in eV) is transferred to the thermal energy of the strip by the electron?
