If a current 5.0 A lags the applied voltage 230 V by an angle ϕ, it can be resolved into two components, OA in phase with the voltage and OB lagging by 90°. If the phasor diagram in to a circuit possessing resistance and inductance in series, OA and OB must not be labelled   and respectively. It has become the practice to say that the power factor is laggingwhen the current lags the supply voltage, and leading when the current leads the supply voltage. This means that the supply voltage is regarded as the reference quantity.   (a) A 30 μ F capacitor is connected across the applied voltage, 50 Hz supply. Calculate the reactance of 30 μ F capacitor connected across applied voltage (b) the reactance of the capacitor; (c) the current.

Is the power factor in Question 6 a leading or lagging power factor? Explain your answer.

The real power delivered by a source to two impedances, Z1=4+j5 and Z2=10 connected in parallel, is 1000 W. Determine (a) the real power absorbed by each of the impedances and (b) the source current.

NEED ASAP please solve this problem,Maximum Average Power Transfer. Please show full and complete solution Note: Answer from the book for Pmax is lower than 50W

Find the following: the power drawn by the 100ohm variable resistor If the variable resistor is set to 200-ohms, instead of 100-ohms, What is the power drawn by the 200-ohms resistor? total current of the system Is the circuit inductive, capacitive, or neither (resistive)? NOTE: Polar form for Voltage & Current. Rectangular form for Impedance

A certain generating plant in manila has 40kV, three phase transmission line to supply a 12MVA load at 30kV and 0.8 power factor. Find the resistance and reactance of the line if the length of the transmission line is 4,000 meters and the efficiency is 88%.
