Answer #1

The instrument used for measuring very small electrical currents is call a Galvanometer.

A galvanometer is the most sensitive apparatus to measure very small current among the all moving-neddle analog meters.Galvanometer is actually a moving coil instrument which measures current by creating a magnetic force proportional to the current and compairing it with restoring force. Other practical moving-coil meters (voltmeter, ammeter etc.) are actually a galvanometer modified to extend measure abilities.

Galvanometer is very sensutive that can measure current of order of magnitude 10 uA while an ammeter can can measure current of order of 1 A current. That's why to measure a very small current we use a Galvanometer.

Polychlorinated biphenyls (PCBs), used in the manufacture of large electrical transformers and capacitors, are extremely hazardous contaminants when released into the environment. The Environmental Protection Agency (EPA) is experimenting with a new device for measuring PCB concentration in fish. To check the precision of the new instrument, seven PCB readings were taken on the same fish sample. The data are recorded in below table (in parts per million). Suppose the EPA requires an instrument that yields PCB readings with a...

Magnets carrying very large currents are used to produce the uniform, large-magnitude magnetic fields that are required for magnetic resonance imaging (MRI). A typical MRI magnet may be a solenoid that is 2.0 m long and 1.0 m in diameter, has a self-inductance of 4.4 H, and carries a current of 750 A. A normal wire carrying that much current would dissipate a great deal of electric power as heat, so most MRI magnets are made with coils of superconducting...

You must write a function that works like a small editor. It should open an existing file (let us say this is File1.txt. This file must exist before the function is run), read it line by line. Then write it to another file (let us say this is File2.txt. This file need not exist since Python will create it). However, if a certain line exists in the first file, it should be replaced by another line supplied by you. You...
