Suppose a generator has a peak voltage of 302 V, and its coil with 500 turns and a diameter of 5.48 cm rotates in a 0.201 T field. At what frequency, in rpm, is the generator operating?

A bicycle generator rotates at 1,975 rad/s, producing a 17.5 V peak emf. It has a 46-turn, 1.00 by 3.00 cm rectangular coil in a 0.640 T field. It is driven by a 1.76 cm diameter wheel that rolls on the outside rim of the bicycle tire. (a) What is the velocity of the bicycle? (Enter the magnitude in m/s.) m/s (b) What is the maximum emf (in V) of the generator when the bicycle moves at 10.0 m/s, noting that it was 17.5 V under the original conditions? V (c) If the sophisticated geherator can vary its own magnetic field, what field strength (in T) will it need at 5.00 m/s to produce a 9.00 V maximum emf?

X2. A transmission line that has a resistance per unit length of 4.50x10−4 /m is to be used to transmit5.00 MW across 400 mi (6.44x105 m). The output voltage of the source is 4.50 kV. (a) What is the lineloss if a transformer is used to step up the voltage to 500 kV? (b) What fraction of the input power is lostto the line under these circumstances? (c) What If? What difficulties would be encountered in attemptingto transmit the 5.00 MW at the source voltage of 4.50 kV?
