Precisely 3.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.10 m/s2 , how much time passes before the police car overtakes the speeder after the speeder passes (assumed moving at constant speed)? t t = 3 s

The answer would be a) -80of

Ibelieve that the correct answer is: c. along plate boundaries

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
