A generator uses a coil that has 350 turns and a 0.27-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made. N S Number i Units vWhat voltage is needed to create a current of 37 mA in a circuit containing only a 1.0-HF capacitor, when the frequency is 3.8 kHz? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. Number i Units
