- Consult Multiple-Concept Example 11 for background material relating to this problem. A small rubber wheel on the shaft of a bicycle generator presses against the bike tire and turns the coil of the generator at an angular speed that is 45 times as great as the angular speed of the tire itself. Each tire has a radius of 0.326 m. The coil consists of 167 turns, has an area of 4.82 x 10-³ m², and rotates in a 0.0889-T magnetic field. The bicycle starts from rest and has an acceleration of +0.658 m/s². What is the peak emf produced by the generator at the end of 6.02 s? Number UnitsA student needs to reduce the percent power loss by 100 times by using a transformer. What would the type and required ratio for the transformer of the windings (primary:secondary)? O step-down: 1 to 10 Ostep-down: 10 to 1 O step-up: 10 to 1 step-up: 1 to 10In which case does the magnetic flux through the loop increase? In which case does the induced current flow in the counterclockwise direction?
- A step up transformer is used to supply a 3.6 kV potential to a spark plug. The primary coil is supplied with a 12 V emf from a battery that has been converted to AC. If the primary coil has 100 turns the number of turns in the secondary should be (a) 300 (b) 2500 (c) 30000 (d) 1080000 (e) 40000The coil on the left is connected to a battery and a switch. The switch is closed causing a counterclockwise current to circulate in the loop on the left (a) There will be no current in the coil on the right (b) a clockwise current will momentarily circulate in the coil on the right (c) a constant clockwise current will circulate in the coil on the right (d) a counterclockwise current will momentarily circulate in the coil on the right (e) a constant counterclockwise current will circulate in the coil on the rightA single loop is made around the center of a solenoid with a length of 20 m and a radius of 5m. How many turns must the solenoid have for the loop and the solenoid to have a mutual inductance of 1 henry?
