Two identical resistors R are connected in series between the positive and negative terminals of a battery. A third resistor Rv, whose resistance can be varied, connects the junction of the two series resistors directly to the negative terminal, forming a second loop. Predict qualitatively how decreasing Rv affects the current through (i) the upper series resistor and (ii) the lower series resistor. Provide your answer as “increase,” “decrease,” or “no change” for each resistor, in that order.
