... The voltage across each resistor is given by Equation 20.2 as V = IR. Because the current through each resistor is the same, the voltage across each is proportional to the resistance. Since R1 > R2 > R3 , the ranking of the voltages is V1 > V2 > V3 . (b) The three resistors are in parallel, so the s ...
