The total current delivered to a number of devices connected in parallel is the sum of the individual currents in each device. circuit breakers are resettable automatic switches that protect against a dangerously large total current by “opening” to stop the current at a specified safe value. a 1650 w toaster, a 1090 w iron, and a 1250 w microwaved oven are turned on in a kitchen. as the drawing shows, they are all connected through a 20 a circuit breaker to an ac voltage of 120 v. (a) find the equivalent resistance of the three devices. (b) obtain the total current delivered by the source and determine whether the breaker will “open” to prevent an accident.

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?
