An AC current of frequency 50Hz is passed through a coil that is magnetically coupled to a second coil. The mutual inductance between the coils is 100mH. The second coil is connected to a high impedance voltmeter (i.e. draws no current) that reads 150V. Determine the magnitude of the current flowing in the first coil.

Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of -0.242 A/s, the induced emf in the second coil has magnitude 1.65 x 10-3 V and the mutual inductance of the two coils is 6.82 mH. If the current in the first coil becomes constant, what happens to the mutual inductance?

An AC source of rms voltage 50 V and frequency 150 Hz is connected to the primary coil of a transformer that has 5000 turns on the primary side and 7500 turns on the secondary side. If the secondary coil is connected to a 150 ohm load, determine the current flowing through the primary coil. 0.75 A 1.25 A 0.25 A 0.50 A

The current through a coil as a function of time is represented by the equation I(t) = Ae−bt sin(ωt), where A = 5.25 A, b = 1.75 ✕ 10−2 s−1, and ω = 375 rad/s. At t = 0.880 s, this changing current induces an emf in a second coil that is close by. If the mutual inductance between the two coils is 4.35 mH, determine the induced emf. (Assume we are using a consistent sign convention for both coils....

Please read the article and answear about questions. Determining the Value of the Business After you have completed a thorough and exacting investigation, you need to analyze all the infor- mation you have gathered. This is the time to consult with your business, financial, and legal advis- ers to arrive at an estimate of the value of the business. Outside advisers are impartial and are more likely to see the bad things about the business than are you. You should...
