equivalent resistance การใช้

• Then find the equivalent resistance of that whole 10-resistor network.
• Find the equivalent resistance in loop 1 and hence find the current in the loop.
• Where R 1 | | R 2 denotes the equivalent resistance of R 1 and R 2 connected in parallel.
• This occurs when the load resistance ( of the device in question ) is equal to the internal Thevenin equivalent resistance of the power source.
• In particular, any current that is shunted away from the load into the Norton equivalent resistance R _ s will be supplied by the INIC instead.
• It is only necessary that the " 2R " value matches the sum of the " R " value plus the Th関enin-equivalent resistance of the lower-significance rungs.
• Resistors which are in " parallel " may be grouped together into a single " equivalent resistance " in order to apply Ohm's law in analyzing the circuit.
• At each stage, resistors for the " rung " and " leg " are chosen so that the rung value matches the leg value plus the equivalent resistance of the previous rungs.
• The equivalent resistance of the workpiece and thus the efficiency is a function of the workpiece diameter a over the reference depth d, increasing rapidly up to about a / d = 4.
• In cases where there is heat transfer through different media ( for example, through a composite material ), the equivalent resistance is the sum of the resistances of the components that make up the composite.
• The noise generated at the resistor can transfer to the remaining circuit; the maximum noise power transfer happens with impedance matching when the Th関enin equivalent resistance of the remaining circuit is equal to the noise generating resistance.
• The equivalent resistance of all the resistors connected to logical " 1 " and the equivalent resistance of all the resistors connected to logical " 0 " form the two legs of a composed voltage divider driving the transistor.
• The equivalent resistance of all the resistors connected to logical " 1 " and the equivalent resistance of all the resistors connected to logical " 0 " form the two legs of a composed voltage divider driving the transistor.
• To obtain exactly the same outcome voltages at the nodes for each problem, the equivalent resistances in the two circuits must be the same, this can be easily found by using the basic rules of series and parallel circuits:
• In S-P and P combinations, the rheostat is divided in three branches connected in parallel; this lowers the overall rheostat equivalent resistance to about 3.5 ohm, while in S combination its elements are all connected in series.
• RSPF represents each net as an RC " pi " model, which consists of an equivalent  near " capacitance at the driver of the net, an equivalent " far " capacitance for the net, and an equivalent resistance connecting these two capacitances.
• Now build the network again, but use the resistors in the reverse order ( so the " innermost " resistors from the first network become the " outermost " resistors in the new network, and vice versa ), and measure the equivalent resistance of that network.
• The voltage of a node referenced to ground is still the sum of the drops across all the resistors, but it's now easier to consider all these resistors as a single equivalent resistance R T, which is simply the sum of all the resistances between the node and ground, so the node voltage is given by V * R T / R eq.
• If one connects two electrical resistors in parallel, one having resistance " x " ( e . g ., 60 ? ) and one having resistance " y " ( e . g ., 40 ? ), then the effect is the same as if one had used two resistors with the same resistance, both equal to the harmonic mean of " x " and " y " ( 48 ? ) : the equivalent resistance in either case is 24 ? ( one-half of the harmonic mean ).
