Question

Multiple-Choice Homework Problem 13.2 A simple transformer has four leads two leads for the primary and two leads for the secondary. If a resistance meter is used to measure the resistance between one of the primary leads and one of the secondary leads, what should be found? Select One of the Following: (a) approximately zero resistance (b) sometimes zero resistance arid sometimes a large resistance depending one which of the primary leads are matched with which of the secondary leads (c) a non-zero resistance, but not a very large resistance (d) approximately infinite resistance Multiple-Choke Homework Problem 13.6 A simple generator is constructed by rotating a flat coil in a uniform magnetic field. Suppose we rotate a flat coil of radius 20m and 400 turns in the earth?s magnetic field 6 times per second so that the surface normal to the coil as parallel to the field once per revolution. The earth?s this generator. Multiple-Choice Homework Problem 13.10 The solenoid forming the secondary of Anthony's Tesla coil has 500 turns wrapped on a tube of radus 9cm and length 80cm(I'm gung the numbers here).If the solenoid carries a current of 1 x 10^-3A, how much energy is stored in the solenoids magnetic field

Explanation / Answer

Note: As per Guidelines, I answer one question, please post other questions separately. (In the case of different questions)

13.2

In transformer the primary coil and secondary coil are not in contact. They are individual coils, so, the resistance between them is infinite.

Therefore, the correct option is (d)
