Suppose a power station is located 50 miles from a power plant and electricity is transported via cables that have an internal resistance of 2 Ω / mile. Thanks to a transformer, the power dissipated across this distance is only 178 W. Power output of the transformer is 400 kW. If input at the power plant is supplied through a 100 A current, what is the ratio of the number of turns in the secondary coil to the number of turns in the primary coil?
Answer should be 75

The switch in an effective LR series dc-circuit (consisting of an emf and a coil with inductance L = 0.5 H and unknown internal resistance) is closed at t = 0 sec. At t = r, the current is 9.5 A and is increasing at a rate of 1.1 A/s. What must the internal resistance of the coil be?

Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...

An average power of 65 kW is delivered to a distant farm via a transmission line that has a resistance R = 3.00 Ohm. The generator has an rms voltage V_1 = 500 V. A step-up transformer raises the voltage to an rms value V_2 = 10,000 V. Calculate the following: The rms value I_2 of the current on the transmission line The average thermal power (P_thermal) lost on the transmission line. The rms...
