Problem 23.43 A rectangular coil 23 by 39 has 140 turns. This coil produces a maximum emf of 61 when it rotates with an angular speed of 180 in a magnetic field of strength . Part A Find the value of . Express your answer using two significant figures. ANSWER: = 27 Correct Transformers Learning Goal: To understand the concepts underlying 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 always present due to the practical requirements of energy distribution. On the one hand, the voltage supplied to 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 of that order). On the other hand, the voltage used in transmitting electric energy must be as high as possible to minimize losses in the transmission lines. A device that uses the principle of electromagnetic induction to increase or decrease the voltage by a certain factor is call
