1. the maximum current output of a 60 ω circuit is 11 a. what is the rms voltage of the circuit?

2.a step up transformer used in an automobile has a potential difference across the primary of 2200 v and a potential difference across the secondary of 25 v. what is the ratio of the number of turns of wire on the primary to the number of turns on the secondary?

What are two different ways you could find the value of a? explain these methods.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

Decreased sensitivity to an unchanging stimulus is known as
