A small sports car and a pickup truck start coasting down a 10.0m hill together, side by side. Assuming no friction, compare the velocity of each vehicle at the bottom of the hill?

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

The best answer i can think of is b

Gotta have a picture ^^

Ai think hope that
