		The most common example is in power supplies where the output voltage is sensed through a voltage divider, compared to a reference through an error amplifier circuit, and adjusted under control of the amplified error signal.
		The precision with which the desired parameter is controlled is a function of many variables, one of which is the voltage division network used to sense the voltage representing the controlled parameter.
		For voltage divider applications, it is the resistance ratio that is important, not the absolute value of the resistors.

	Voltage Dividers and Attenuators
		A voltage divider is created whenever you have two resistors (or impedances) in series, with the signal "take-off" point between the two.
		A traditional voltage divider is shown in Figure 1, and this is the form taken by volume and balance controls, general purpose attenuators, and similar configurations.
		It is essential that any attenuator or voltage divider is driven from a low impedance source, or the load of the divider itself will reduce the available voltage (the formula shown will appear to be in error).

		Voltage Division Resistors are circuit elements designed to provide a linear voltage-current characteristic, that is, to follow Ohm’s Law.
		If the voltage across the series combination is known, voltage division may be applied to find the distribution of voltage across the resistors.
		Here, the current is supplied by a voltage source and resistor, but it is important to realize that current division works the same way regardless of the source of the current through the parallel combination.

	Voltage division
		The voltage dropped across each resistor is proportional to the resistance value of that resistor.
		The voltage division formula is used twice, first to find the voltage across R4, and second to find the voltage across R2.
		This is done using the voltage divider formula to find the portion of Vs appearing between these two nodes.

	Balanced out line stage (page 6)
		This means half the B+ voltage would appear at the cathode of the Split-Load phase splitter and half of voltage would appear at the plate, leaving 0 volts across the triode.
		Because the voltage division is meant to be performed solely on the DC component of the plate voltage, the top resistor must be capacitor bypassed and the resistor values can be extremely large, 1 to 10 meg.
		Place a 50% voltage divider between B+ and ground; feed the output from this divider into the grid of a Split-Load phase splitter; estimate the amount and phase of the power supply noise at the phase splitter's outputs.

	Circuit Analysis Techniques
		As you saw in the last lab, the voltage-current relationship for a resistor is V = IR where V is voltage* measured across the resistor (in Volts), I is the current through the resistor (in Amperes, or Amps), and R is resistance value of the resistor (in Ohms).
		The water pressure corresponds to voltage, the current is the flow rate, and the resistance is shown by constrictions in the pipes.
		Verify KVL by using voltage division to calculate the voltages across R1, the pair R2R3, the pair R4R5 and the series sum R6+R7, and then adding the voltages around the loop.

	Step Responses on the HP 54600B Oscilloscope
		Typically the time sweep is too fast, and the voltage scale is set too small to measure the quantities needed in the lab.
		Under the default set-up, the voltage per division (per grid block) is 100 ms.
		A good strategy to use to get the scales set right is to set both the voltage and the time scales as coarse as possible.

		The time constant of a capacitance C and a resistance R is equal to CR, and represents the time to change the voltage on the capacitance from zero to E at a constant charging current E / R (which produces a rate of change of voltage E / CR across the capacitance).
		If a voltage E is applied to a series circuit comprising a discharged capacitance C and a resistance R, then after time t the current i, the voltage v

	Basic DC Theory
		There are four quadrants representing Voltage, V, Power, W, Resistance, R and Current, I. Knowing any two quantities allows the other two to be found.
		The side of the resistor where the current flows into the resistor will be the positive side of the voltage, the negative side is where the current flows out.
		The voltage on the left hand 10 ohm resistor is flowing out of the top terminal of the resistor.

	Voltage and current division
		Notice that at this frequency, with these component values, the magnitudes of the two voltages are nearly the same, but the phases are of opposite sign.
		It also demonstrates Kirchhoff’s current law (KCL), showing that the current IS entering the upper node of the circuit equals the sum of IL and IR, the complex currents leaving the node.
		The component values and the source voltage, frequency, and phase are given on the schematic below.
