a) Show that the interconnection of the elements satisfies the power check. b) Find the value of the current through each of the elements using the values of power and voltage and the current directions shown in the figure.

Three resistors are connected in parallel namely R1, R2 and R3. It is impressed by a source voltage of 120V. If R1 receives 15W while R2 carries a current if 100mA, what should be the value of resistance R3 if the power supplied by the voltage source is 60W?   a. 364.4 ohmsb. 436.4 ohmsc. 43.64 ohmsd. none of these

A wye connected load whose impedance is 15 W (resistance) per phase, a three phase motor that draws a total of 12 kVA at 0.65 lagging pf and a balanced delta load whose impedance is (16 + j 45) ohms per phase are supplied from a three-phase, 208 V, 60 Hz feeder. Determine the overall power factor of the feeder loads.

5. Consider the resistor network connecting points A and B in the figure be- low. What is the equivalent resistance between points A and B? If the potential difference between A and B is 12 volts, what is the current in the 4 2 resistor? What is the rate at which heat is produced in the 42 resistor? 1 12n
