Imagine a single-loop circuit with a battery, and three resistors R1, R2, R3 connected in series. Resistance is ignorable except for the resistors. Resistors are ohmic. Answer the following question. a. (0.5) Which (if any) physical quantity- among resistance R, current I, and voltage V must be the same for the three resistors?
b. (0.5) How are R, I, and V related for each resistor in this circuit? Answer with an equation involving these three quantities.
