Ch. 15: Electric Forces and Electric Fields
... Recall that the gravitational force, Fg = G m M / r², is a conservative force because the work done to move a particle from point A to point B in a gravitational field depends only on the locations A and B, but not on the path taken from A to B. Because the electrostatic force has the same form as t ...

... light through the length of the laser due to longitudinal mode beating. I have two lasers of different lengths with one producing 437 Mhz and the other 635 MHz. The signals slowly ( over a few seconds) sweep back and forth about 100 KHz probably due to warm up of the tubes and related mode changes. ...

The same force acts between two charged fields when the distance r between the sphere midpoints is significantly greater than the sphere diameter, so that the uniform charge distributions of the spheres is undisturbed. In other words, the spheres in this geometry may be treated as points. In this ex ...

Galvanometer
A galvanometer is a type of sensitive ammeter: an instrument for detecting electric current. It is an analog electromechanical actuator that produces a rotary deflection of some type of pointer in response to electric current through its coil in a magnetic field.Galvanometers were the first instruments used to detect and measure electric currents. Sensitive galvanometers were used to detect signals from long submarine cables, and to discover the electrical activity of the heart and brain. Some galvanometers use a solid pointer on a scale to show measurements; other very sensitive types use a miniature mirror and a beam of light to provide mechanical amplification of low-level signals. Initially a laboratory instrument relying on the Earth's own magnetic field to provide restoring force for the pointer, galvanometers were developed into compact, rugged, sensitive portable instruments essential to the development of electrotechnology. A type of galvanometer that records measurements permanently is the chart recorder. The term has expanded to include use of the same mechanism in recording, positioning, and servomechanism equipment.
