Calculate the peak voltage of a generator that rotates its 200 urn, 0.100 m coil at 3600 rpm in a 0.800 T field.

A generator produces 21.0 V when turning at 890 rev/min. What emf does it produce when turning at 530 rev/min? V

A 24.0 V battery is attached to a 0.180 m long solenoid with 2600 turns. It creates a 0.0705 T field. What is the resistance of the coil? (Hint: What is the current?) (Unit = Ohms)

A bicycle generator rotates at 1,800 rad/s, producing a 15.5 V peak emf. It has a 45-turn, 1.00 by 3.00 cm rectangular coil in a 0.640 T field. It is driven by a 1.48 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 15.5 V under the original conditions? V (c) If the sophisticated generator 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?

Calculate the peak voltage of a generator that rotates its 215 turns, 0.100 m diameter coil at 3600 rpm in a 0.660 T field. _____V

A simple AC generator consists of 20 coils of wire with an area of 1 000 cm2 and placed in a region where the magnetic field is 0.5 T. How long will it generate a peak electromotive force of 220 V?

A 24.0 V battery is attached to a 0.180 m long solenoid with 2600 turns. It creates a 0.0705 I field. What is the resistance of the coil? (Hint: What is the current?) (Unit = Ohms)
