Document Summary
Name ______________________________________ student id _______________ score________ last first. [20 points total] for the following questions, assume that the switch and all wires are ideal conductors. Also assume the battery is simple and ideal, with the positive terminal oriented toward the top of the page: a battery is connected in series with two identical resistors. An open switch (represented by a gap) is connected in parallel to the lower resistor as shown: on the diagram, draw an arrow to indicate the direction of the electric field at each point. If the electric field at any point is zero, state so explicitly. Chemical reactions in the battery push positive charges to the upper terminal and negative charges to the lower terminal, so the electric field is down. Charges move down through the resistor, which means the resistive force points up. Since charges move at constant speed, the electric field points down.
