A 240V three phase power system supplies two loads in parallel: Load 1: measured line current 30A, power factor 0.85 lagging, and Load 2: measured power 10kW, reactive power -7.5kVar. A. Determine the power factor of load 2. B. Determine the total real power (in kW), reactive power (in KVAR), apparent power (in kVA), power factor and line current (in A) of the two loads.

What do you think will happen to a load that was rated at 1.8v, 35mA if it was connected on a 5v power supply? Is the current setup provides optimal operation? or is there better construction for the circuit? Considering that you are only going to use the given power supply and the load?
Compute the capacitance of the capacitor in the defibrillator and calculate the magnitude of the averagecurrent flowing during the pulse.Hint: The relation between the stored charge (Q), and the voltage across the capacitor is given byIn a charged capacitor, positive charges are on one side of the plate, and negative charges are on the other.The amount of energy (E) stored in such a configuration is given byCurrents in the range of a few amperes flowing in the region of the heart can cause death within a few minutes. In thisconnection, a large current of about 10 A is often less dangerous than a 1-A current. When the smaller current passes through the heart,it may tetanize only part of the heart, thereby causing a desynchronization of the heart action; this condition is called fibrillation. Themovements of the heart become erratic and ineffective in pumping blood. Usually fibrillation does not stop when the current source isremoved. A large current tetanizes the whole heart, and when…
