The reciprocal method must then be used to find total resistance. The reciprocal
method is as follows: 1 RT R 1 1 1 R2 1 R3 1 Rn — = — + — + — + ... + — The
total resistance of a parallel circuit is not equal to the sum of the resistors, as in
series circuits. When more branches are added to a parallel circuit, the total
current (IT) increases. In a parallel circuit, the total resistance is less than any of
the branch resistances. As more parallel resistances are added, the total
resistance of the ...

There are two simple rules used to determine how many vessels of different sizes
combine to give a single resistance to flow. In a system composed of
differentsized tubes arranged in series (i.e., sequentially, or end-toend), the total
resistance of that system is simply the sum of the individual resistances. Or, R. ...

segment of a tapering artery where the proximal 1 cm of length had an R = 1 PRU

In other words, all of the parallel resistances could be replaced by a single
resistor with a value of R, that would draw I,. The more resistors that are added in
parallel, the higher the total current that is drawn from the source, and the lower
the total equivalent resistance of the circuit. The total resistance of a parallel
circuit, as it turns out, is less than the smallest value resistor. You can verify this
yourself by referring back to the circuit in Fig. 3-9. All you do is divide the source
voltage, ...

Notice that this is the same total that we found when we figured the total
resistance by dividing the applied voltage by the total current flow in amps.
Figuring total resistance by looking at individual resistances and using the
previous formula will show that, as additional resistances are added in parallel,
the total will always go down to a level lower than the lowest resistance. Add an
additional bulb to our two-bulb circuit. Measure the amperage and the applied
voltage. Insert the figures ...

1-2) is important because parallel vessels decrease total vascular resistance.
When there is a parallel arrangement of resistances, the reciprocal of the total
resistance is equal to the sum of the reciprocals of the individual resistances. For
example, the total resistance (RT) of three parallel resistances (R1,R2, R) would
be: 1 1 1 1 R. R. " R. " R, or solving for Rr, Eq. 5-7 R1 = --- R. "R," R, Two
important principles emerge from Equation 5-7. First, the total resistance of a

Alternatively, to find total resistance, we can use the following equation: RT=(Ri
xR2)/(R where RT = total resistance, R, = value of resistance 1, and Ri = value of
resistance 2 Eq. 6.8. Alternate equation to calculate total resistance for a circuit
with several resistances wired in parallel In this example, we get RT = (1 X 2)/(l +
2) = 2/3 n total resistance. If there were more resistances, we would simply
continue this process in pairs using our current result (2/3 Q) as the next Rj. Now
that we ...
