what is the effect of changing the wire in a circuit from a straight thick wire to a longer (coiled) thick wire?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

The pressure proportional to the area a- inversely b- directly c- increase d-decrease
