A ball of plasticine is released from rest at height of 2.2 m above the ground. After touching the ground, the plasticine ball comes to rest in 96 ms. Determine the average acceleration (magnitude and direction) of the plasticine ball while coming to rest

Centrapedial force is the answer

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
