1- The following experimental data belong to a three-phase
synchronous motor, which is being powered by a three-phase voltage
source of 208 V. The current I1 is the magnitude of the stator line
current (in amperes), while the current I3 is the DC excitation
current in the rotor winding (in amperes). The readings of the
method of the two wattmeters are identified by W1 and W2 (in
watts). Calculate the actual input power Pse to the motor in watts
(W),...

XCO DE Problems 1-3 are based on the following description Electrical energy is applied to a system enclosed inside the piston-cylinder device shown below. The voltage is 10 volts and the current is 2 amps for 20 seconds. During this time there is a heat transfer from the system to the outside equal to 90J, the system expands 0.2 m at a constant pressure of 200 kPa. The amount of electrical energy in J applied to the system is closer...
