Solve the following problems and include your complete solution. A. A wattmeter with its current coil in line 2 and potential coil across lines 2 and 3 is connected to a balanced 3-phase system. The only load supplied is a single-phase one connected to lines 1 and 2. This load is known to be inductive. If the wattmeter reads zero watts, determine the power factor of the single-phase load. B. Two batteries A and B are connected across each other with terminals of the same polarity together. The open-circuit emf and internal resistance of each battery is respectively 24 V and 1.5 Ω. Determine the resistance of a heating load connected across the parallel combination of batteries so that the power consumed in the load is 100 watts.
