Anosh gets two bulbs of the following power ratings to add ambience to his study desk.
Bulb Power rating
A 14 V/28 W
B 14 V/4.0 W
He connects them in parallel across a 7.0 V battery, as shown.

What is the power dissipated by each bulb?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
