50 electric bulbs are connected across supply of 220 volts. After one bulb is fused remaining 49 bulbs are again connected to same supply. The illumination will be more with 50 bulbs than with 49 bulbs. True False In two heating coils one is thinner and the other is thicker. Both coils are of same material and length. These are connected in parallel and then in series. In parallel combination thicker wire liberates more energy and in series combination thin...

Helmholtz coils are a method developed to provide a uniform magnetic field in a small region. They are constructed by placing two identical wire loops parallel to each other, separated by a distance equal to their radii, as shown in the Figure. Assume that the two loops are also connected in parallel to a power supply, so that they produce the same field. (a) Find the length of a 28-gauge copper wire that will produce a 75 Ω coil. m...

Consider a solenoid connected to DC power supply such that magnetic field is pointing out of the solenoid on the end that is facing you. a) A metal bar about 50% longer than the solenoid is inserted halfway into the solenoid. Does the metal bar experience any force from the solenoid? b) If so, in what direction? c) With the metal bar removed, if you were to attempt insert a bar magnet from the solenoid side where the magnetic field...

Consider two very long conducting parallel wires carry currents in opposite directions such that one is triple of the other. The distance between wires is 30 cm. The magnetic field at points on a line between the wires, and at a distance of 5 cm from the wire carrying the smaller current, is 2.5×10-5 T. a) Draw a diagram of the situation. Assume the wires are placed in the x-direction. Draw the direction of the magnetic field at points on...

Imagine you have two wire loops lying next to each other on a table. The first one is connected to a DC power supply (like a battery), producing a constant current through the wire, which in turn produces a magnetic field. The second wire loop reacts to this magnetic field according to Faraday's law. Does the second wire loop have any current flowing through it? Why/how is this situation different than with the AC power supply in the previous question?

1. A wire W1 of some resistance is connected to a batter with potential V, and dissipates a power P1. A second wire W2, twice as long as W1, is connected to the same battery, and dissipates a power P2 = 2P1. From this we can conclude: a) The wires must be made of the same material. b) The wires must have the same cross-sectional area. c) The resistance of W1 must be less than that of W2. 2. Two...
