At a certain location, Earth's magnetic field of 53 µT is horizontal and directed due north. Suppose the net field is zero exactly 7.5 cm above a long, straight, horizontal wire that carries a constant current. What is (a) the magnitude of the current (in A) and (b) the angle between the current direction and due north?

How much power does this air conditioner draw : An air conditioner draws 12 A at 220 V ac. The connecting cord is copper wire with a diameter of 1.450 mm. how much power does this air conditioner draw? If the total length of wire is 18 m, how much power is dissipated in the wiring?

Charged particle moves through space with constant velocity : A charged particle moves through space with constant velocity (magnitude and direction). If the external magentic field is zero in this region, you can conclude that the external electric field in this region is also zero.

Light bulbs-which one burned out and why : You have two 120V light bulbs, one 25W and one 100W, that are normally connected in parallel with 120V across each. Your friend had what seemed like a good idea which was to connect them in series across a 240V power line. However, one of them burned..
