A hand crank generator is used to power a light bulb. The person turning the crank uses 22 Newtons of input force to turn the crank 8 revolutions in 3 seconds. Each revolution of the crank equals 0.3 meters of distance that his hand moves. A multimeter connected to the light bulb records 0.08 amps of current and 9.04 volts.
1. Calculate the input power of the hand crank generator in Watts.
2. Calculate the output power of the hand crank generator in Watts.
3. Calculate the efficiency of the hand crank generator.
