A belt of negligible mass passes between cylinders A and B and ispulled to the right with a force P. Cylinders A and B weigh, respectively, 5 and 20 lb. The shaft of cylinder A is free to slide in avertical slot and the coefficients of friction between the belt and eachof the cylinders are µs = 0.50 and µk = 0.40. For P = 3.6 lb, determine(a) whether slipping occurs between the belt and either cylinder,(b) the angular acceleration of each cylinder.

Sorry i don’t know what to do

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
