Analyzing Unknown AC Circuit Elements O points possible (ungraded) Eſt) ? R The circuit shown above contains an AC generator with V (t) = V sinut, a resistor with resistance R, and a "black box", which contains either an inductor or a capacitor, but not both. In general, the current in the circuit is given by I(t) = Iosin (wt - o), where V Io (1) (R2 + (wL - 1/WC)3,1/2 - and WL-1/wC tano = R (2) In the above equations: a) if there is no capacitance in the circuit set C = 0, then 1/C = 0, (note that infinite capacitance means that the capacitor can be treated like a resistanceless Wire); b) if there is no inductance set L=0. In the circuit above, the amplitude of the voltage source is, Vo = 200V, and the angular frequency w = 5rad.s-1. We measure the current in the circuit and find that the amplitude Io = 10A and the phase constant o = 7/4. (Part a) Does the current lead or lag in time the voltage source? lead lag
Analyzing Unknown AC Circuit Elements O points possible (ungraded) (Part b) What is the unknown circuit element in the black box - an inductor or a capacitor? inductor capacitor Submit Analyzing Unknown AC Circuit Elements 0 points possible (ungraded) (Part c) What is the numerical value of the resistance R? R= 12 Submit Analyzing Unknown AC Circuit Elements 0 points possible (ungraded) (Part d) What is the numerical value of the capacitance or inductance, as the case may be? C or L = in For H
Analyzing Unknown AC Circuit Elements O points possible (ungraded) (Part e) What value of C or L should be connected in series (in addition to the “mystery" element that is already there) for the circuit to be in resonance with the given driving angular frequency? What would be the amplitude Io of the new current? C or L= in For H Io = = A
