Notes This circuit measures radio field strength by converting the signal to DC and amplifying it. They can be combined with our NEMA and IEC motor starters, overload relays, and contactors. A junction is a point where at least three circuit paths meet. An op-amp has two inputs and it amplifies the voltage difference between those two inputs. Measurement circuits are of high impedance, however, and under these conditions 1 volt rms may be applied even to 6 volt capacitors (23% peak reversal) without a DC bias. 286 amps, we found using Kirchhoff's circuit law in the previous circuit analysis tutorial. And there are follow on courses that talk about waveguides and other distributed analysis techniques that deal with signals that travel close to speeds of light.
