An ideal transformer steps down 120 V to 12 V and the 2630-turn secondary supplies 12 A of current through a load of 1 ohm. (a) Determine both the rms average current and the peak current in the primary. (b) What is the number of turns in the primary? (c) What is the ratio of power in the secondary to the power in the primary?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
