	The "Unbalanced" Wheatstone Bridge Circuit: Nonlinearity
		The classical Wheatstone bridge arrangement has been used for many years for the accurate measurement of a single unknown resistance; and, in such instruments, the bridge is balanced at the time of measurement by adjusting the resistances of the other arms.
		The bridge circuit found in most strain indicators, on the other hand, is unbalanced by the varying gage resistance(s) at the time of making the measurement, and is therefore commonly referred to as the "unbalanced" Wheatstone bridge.
		The output voltage obtained from the "unbalanced" Wheatstone bridge is a function of the amount of unbalance, and is therefore directly related to the strain applied to the strain gage.

	Bridge Rectifier
		Bridge rectifier consists of four diodes connected in a bridge circuit that provides the output voltage of same polarity for any polarity of the input voltage.
		Bridge rectifier is used for conversion of alternating current (AC) input into direct current (DC) output.
		Thus in a diode bridge circuit, the peak output will be lower than the peak input by an amount equal to twice this value.

	Bridge circuit Summary
		A bridge circuit is a type of electrical circuit in which the current in a conductor splits into two parallel paths and then recombines into a single conductor, thereby enclosing a loop.
		The best-known bridge circuit, the Wheatstone bridge, was invented by Samuel Hunter Christie and popularized by Charles Wheatstone, and is used for measuring resistance.
		In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e.

		They are a bit simplified from their real-life counterparts, as practical symmetrical bridge circuits often have a calibrated, variable resistor in series or parallel with the reactive component to balance out stray resistance in the unknown component.
		This ingenious bridge circuit is known as the Maxwell-Wien bridge (sometimes known plainly as the Maxwell bridge), and is used to measure unknown inductances in terms of calibrated resistance and capacitance.
		Unlike the plain Wien bridge, the balance of the Maxwell-Wien bridge is independent of source frequency, and in some cases this bridge can be made to balance in the presence of mixed frequencies from the AC voltage source, the limiting factor being the inductor's stability over a wide frequency range.

		All four arms of the bridge are active; two are in tension and the two on the opposite side are in compression.
		A Wheatstone bridge circuit is widely used to convert the gauge's microstrain into a voltage change that can be fed to the input of the A/D converter (ADC), as shown in Figure 1.
		When used with an instrument, a strain gauge replaces one or more of the resistors in the bridge, and as the strain gauge undergoes dimensional changes (because it is bonded to a test specimen), it unbalances the bridge and produces an output voltage proportional to the strain.

		A diode bridge or bridge rectifieris an arrangement of four diodes connected in a bridge circuit as shown below, that provides the same polarity of output voltage for any polarity of the input voltage.
		The bridge recitifier provides full wave rectification from a two wire AC input (saving the cost of a center tapped transformer) but has two diode drops rather than one reducing efficiency over a center tap based design for the same output voltage.
		When the input connected at the left corner of the diamond is positive with respect to the one connected at the right hand corner, current flows to the right along the upper colored path to the output, and returns to the input supply via the lower one.

		Unlike the "potentiometer" circuit used to simply measure an unknown voltage, bridge circuits can be used to measure all kinds of electrical values, not the least of which being resistance.
		Wheatstone bridges are considered a superior means of resistance measurement to the series battery-movement-resistor meter circuit discussed in the last section.
		Unlike that circuit, with all its nonlinearities (logarithmic scale) and associated inaccuracies, the bridge circuit is linear (the mathematics describing its operation are based on simple ratios and proportions) and quite accurate.

	BEAM Circuits -- Steve Bolt's H-bridges
		This bridge is "smokeable" -- but only if power is supplied to the bridge while the control inputs are allowed to "float" (easy thing to avoid in your circuit design).
		When I first started tinkering with this circuit, I made the assumption that the inverters pictured in Steve's diagram were not intrinsic parts of the bridge, but instead were examples of the outputs coming from the "driving" circuit.
		This bridge should only be used for high-current motors (too large to be driven by "stacked" 74*245 chips); it has enough "personality" and a sufficiently-high parts count to make it a "special case" driver.

		Wheatstone bridge circuits such as that shown in Fig.2 were first developed to allow very precise measurement of the resistances of samples of materials.
		Similar bridges, substituting known inductances and known capacitances for the resistance arms of the bridge, are employed in the measurement of the inductance and capacitance of circuit components.
		However, instead of trying to constantly adjust R2 to balance the circuit, the galvanometer is replaced by a circuit that can be calibrated to record the degree of imbalance in the bridge as the value of strain or other condition being applied to the sensor.

		Bridge circuits are simple circuits that permit us to solve the problems noted above, and you need to learn about them.
		By now you should realize that it is possible to have the bridge balanced, but it might be unusable because the voltages out of the voltage dividers in the two different arms fall into one of these two categories.
		Summing that up, if you have a resistive sensor and you want to use it in a bridge circuit, the resistor in series with the sensor should be chosen so that the resistance in series has the same value as the nominal resistance of the sensor.
