Why not use near field probes
... This makes it obvious that it is the aerial which radiates emissions, not the source. Near field probes are great for detecting the location and frequency of sources, but they give little information about the efficiency of the radiating mechanism, the aerial. So we can have a situation (and very fr ...

... The current is from A to B. Hence the loop equation (going from A to B) is (guessing the polarity of C): -(Q/C) -40V - 10K (2ma) +30V = 0. Thus Q/C = -30V => Q= -1.5mC. The - sign means that the polarity of C is opposite to what we guessed in the loop equation, so left side is +. 20. The ‘rms’ value ...

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.
