LINEAR VARIABLE DIFFERENTIAL TRANSFORMER
... It indicates that resistance of connecting lead, r has no effect on the measurement, provided that the two sets of ratio arms have equal ratios. It indicates that it is desirable to keep r as small as possible in order to minimize the errors in case there is a difference between ratios P/Q and p/q. ...

... The “2-wire” resistance measurement is inherently inaccurate for low resistances because undesired voltage appears across the lead resistances due to current flowing through them. This source of error can be eliminated by supplying current to the unknown resistance by means of a separate circuit. Th ...

how to find the resistance of loads wired in parallel
... What you are looking for is the total resistance value of a parallel circuit. You can then compare this value to what the circuit would be like if only one single load was wired in series. We call this the parallel circuits’ “equivalent resistance value”. Each load wired in parallel provides an ADDI ...

Resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits.The electrical function of a resistor is specified by its resistance: common commercial resistors are manufactured over a range of more than nine orders of magnitude. The nominal value of the resistance will fall within a manufacturing tolerance.
