Question: Six resistors, all having the same temperatures and compositions, are each attached to a battery with voltage V to form a simple circuit. The resistors

Six resistors, all having the same temperatures and compositions, are each attached to a battery with voltage V to form a simple circuit. The resistors have different lengths, l, but the same diameters. Rank the circuits according to the current that flows through the resistor from smallest to greatest. If two (or more) circuits have the same current flowing, give them the same ranking. Explain the rationale you used to establish your rankings.
Circuit 1: l = 2 cm; V = 3 V
Circuit 2: l = 2 cm; V = 6 V
Circuit 3: l = 1 cm; V = 3 V
Circuit 4: l = 1 cm; V = 6 V
Circuit 5: l = 3 cm; V = 2 V
Circuit 6: l =  3 cm; V = 6 V
