A. We again consider the photoelectric effect apparatus and will assume that the light source is on. Monochromatic light source H Evacuated tube B + Let I, represent the ammeter reading with no battery in the circuit. 1. Is I1, the current when there is one battery in the circuit, greater than, less than or equal to I? Explain. 2. A second battery is added in series with the first; both batteries have the same orientation. Rank I。, I₁, and 12 (the current when there are two batteries in the circuit) according to magnitude, from largest to smallest. Explain. 3. Suppose additional batteries were inserted in the same manner. Would the current increase with each addition? If so, is there a limit to the amount of current that can be produced? Explain. 4. Is it possible to use batteries to decrease the current? If so, show how to connect the batteries and sketch some possible paths of electrons.
