Please show steps and comment
Two ac generators supply the same voltage. However, the first generator has a frequency of 1.2 kHz, and the second has a frequency of 5.7 kHz. When an inductor is connected across the terminals of the first generator, the current delivered is 0.15 A. How much current is delivered when this inductor is connected across the terminals of the second generator? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. Number i Units 1₂ L 0000 V sin 2π f₁t Circuit 1 12 L 0000 Vo sin 2x f₂t Circuit 2

Suppose I have two peak phasor voltages, V, = 100245° and V, = 75Z-60°. Circle Your Choices: I. The frequencies associated with the phasors are (0 Hz, 60 Hz, 50 Hz, Unknown). II. The rms value of the first phasor is (100, 70.7, 141, 200) volts. III. If you want to add these two phasors, the frequencies must be (60 Hz, 50 Hz, The same, Integer multiples of a given frequency.)
