Gerard is riding his bicycle directly east. His maximum instantaneous velocity was 8 meters per second and his minimum instantaneous velocity was 0 meters per second. He covered 7.20 kilometers in 20.0 minutes. What is his average velocity for the ride? 8 m/s
6 m/s
4 m/s
0 m/s

Inner peace.. jk it's  a stable electron configuration

The answer is trial 3.

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
