3) Two thin conducting wires are used to connect very large conducting plates to opposite poles of a battery. Chemical reactions within the battery produce an emf E that "pushes" one electr after another onto the wire connected to the negative terminal of the battery, and "pulls" one electron after another from the wire connected to the positive terminal of the battery on electrons pulled in electrons battery pashed out conducting plate a) Given that positive charges repel each other...

3. A conducting rod hangs from two conducting springs with their upper ends fixed at points X and Y. The rod is in a uniform magnetic field, B, that is directed out of the page. A battery is connected between points X and Y as shown, which results in a current, I, in the rod. The rod is displaced downward and eventually comes to equilibrium Battery Which point, X or Y, is connected to the positive terminal of the battery?...

In the circuit shown in the diagram below, two thick wires connect a 1.4 volt battery to a Nichrome (NIC) wire. Each thick connecting wire is 14 cm long, and has a radius of 9 mm. The thick wires are made of copper, which has 8.35+28 mobile electrons per cubic meter, and an electron mobility of 0.00434 (m (V/m). The Nichrome wire is 8 cm long, and has a radius of 4 mm. Nichrome has 9e+28 mobile electrons per cubic...

PHY 212 Bonus Question for Exam #4 1. In the circuit shown in the diagram, the current in the solenoid (opening is perpendicular to the plane of the page) is in the direction shown (counterclockwise). The current is INCREASING linearly in time. The battery in the circuit has an emf equal to the emf of a single loop around the solenoid. The bulbs are all identical and the internal resistance of the battery is much less than the resistance of...

Two Nichrome wires
The following questions refer to the circuit shown in the figure,
consisting of two flashlight batteries and two Nichrome wires of
different lengths and different thicknesses as shown (corresponding
roughly to your own thick and thin Nichrome wires). The thin wire
is 54 cm long, and its diameter is 0.25 mm. The thick wire is 15 cm
long, and its diameter is 0.39 mm.
(a) The emf of each flashlight battery is 1.5 volts. Determine
the steady-state...

(10 Points. Show your work/explanation for full credit) As shown in the figure, two parallel wires carry a current I in opposite directions, and this current is decreasing. A rectangular loop is centered between the wires. The direction of the induced current through the resistor R is R M a b from b to a. alternating. Therefore, goes from a to b for a moment and then b to a later from a to b. No current is induced. Upload...
