Divers and surfers often use wetsuits when they are spending many hours in the water. The wetsuits have a think layer of water that exists between the material of the suit and the skin of the wearer. Justify the presence of the think layer of water using the data shown here.

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
