Question

A lightning rod is a rounded copper rod mounted on top of
a building and welded to a heavy copper cable running down into the
ground. Lightning rods are used to protect houses and barns from lightning;
the lightning current runs through the copper rather than through
the building. Why? Why should the end of the rod be rounded?

When electric current passes through the metallic filament (Tungsten) of an incandescent light bulb, it makes the filament so hot that it glows and emits light. Assuming that the light bulb is connected to a battery (constant voltage), what happens to the electric current as a function of time during the first few seconds after the light is turned ON? Briefly explain why? (a) it remains steady (does not change) (b) it decreases (c) it increases
A scientist just bought a very cool magnet, and would like to measure it’s strength. She takes a stripof copper with width 3.0cm, and a rectangular cross-section of 0.004m^2 and runs a current of 0.5Athrough it. She knows copper has a free charge density of 8.491× 10^28 m−3. She holds the magnetnear the strip, and measures a voltage across the sides of the strips, and her voltmeter reads 11.2 nV-what is the strength of her magnet?
ou have a summer job as an assistant technician for a telephone company in California.During a recent earthquake, a 1.0-mile long underground telephone line is crushed atsome point. This telephone line is made up of two parallel copper wires of the samediameter and same length, which are normally not connected. At the place where theline is crushed, the two wires make contact. Your boss wants you to find this placeso that the wire can be dug up and fixed. You disconnect the line from the telephonesystem by disconnecting both wires of the line at both ends. You then go to one end ofthe line and connect one terminal of a 6.0-V battery to one wire, and the other terminalof the battery to one terminal of an ammeter. When the other terminal of the ammeteris connected to the other wire, the ammeter shows that the current through the wire is1.0 A. You then disconnect everything and travel to the other end of the telephone line,where you repeat the process and find a current of 1/3 A.

The circuit in the figure consists of switch S, a 5.10 V ideal battery, a 20.0 MQ resistor, and an airfilled capacitor. The capacitor has parallel circular plates of radius 4.90 cm, separated by 5.00 mm. At time t = 0, switch S is closed to begin charging the capacitor. The electric field between the plates is uniform. At t = 150 µs, what is the magnitude of the magnetic field within the capacitor, at radial distance 2.40 cm? Number i S C R Units T
