A piston-cylinder device contains 12 kg of saturated vapor R-134a at 2.4 bar (State 1). A 110 V electric source supplies current to a resistor within the cylinder for 6 minutes and heat transfer of 300 kJ occurs to the system. During these energy interactions, the pressure is maintained constant and the refrigerant is heated to 70oC (State 2). (a) Calculate the current (A) supplied to the resistor.
