An individual is attempting to bench press a 1200 N barbell. The individual pushes against the barbell with a force of 1140 N for 3 seconds, but is unable to lift the barbell. How much work was performed as the individual pushed against the barbell

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

Ibelieve the answer is d. densityhope my answer has you : )
