When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and thus, slows him down. Suppose the weight of the sky diver is 913 N and the drag force has a magnitude of 1010 N. The mass of
the sky diver is 93.2 kg. Take upward to be the positive direction. What is his acceleration, including sign?

Nucleus for question ome

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
