The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. air enters a set of these nozzles at 300 psia and 700°f with a velocity of 82 ft/s and exits at 250 psia and 645°f. calculate the velocity at the exit of the nozzles. the specific heat of air at the average temperature of 672.5°f is cp = 0.253 btu/lbm·r.

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
