A 25- W resistor and a 300-mH inductor are connected in parallel across a 120-V, 50-Hz source. Determine the magnitude of the following: (a) admittance; (b) current through resistor and inductor; (c) the total current; (d) true power and inductive reactive power; (e) apparent power, power factor, and power factor angle.
The currents in each branch of a two-branched parallel circuit are given by the expression
1₁ = 7.07 sin(314t - 4) and 2 = 21.2 sin(314t-3). The supply voltage is given by the
expression v = 354 sin 314t. Derive a similar expression for the supply current and calculate
the ohmic value of the component, assuming two pure component in each branch. State
whether the reactive components are inductive or capacitive.
