A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.

Formula for resistance of a parallel network?
Rtotal = 1 / ( (1/RA) + (1/RB) )
A resistor of 10k ohms resistance with tolerance of 5 percent is connected in parallel with another resistor of 5k ohms resistance and 10 percent tolerance.what is tolerance limit of parallel network?
6.67%
What is the total resistance if they have equal resistances in series in each of rows in parallel?
If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]
Can Norton's theorem be applied to network which contains non linear resistance?
yesAnswerNo it cannot, any more than Ohm's Law can be applied to circuits with non-linear elements.
How do you calculate contact resistance?
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.

Is Resistance 3 Playstation Network?
Yes it is a PS3 game with offline and online cooperative modes
Who is ohm?
Ohm is the SI unit of electrical impedance (AC) or the electrical resistance (DC), named after Georg Ohm. Not Ohms!
How can you find the resistance network using some 1 ohm resistors in order to have minimum resistance?
The minimum possible combined resistance of a handful of resistors, no matter how many or what their values are, is always formed by connecting them all in parallel. The maximum possible resistance always results from connecting them all in series.

What are the factors affecting the electric power industry?
Resistance Resistance is one of the biggest factors affecting power flow in a network. Resistance impedes the flow of electricity. Every element of an electric network has some amount of resistance. The electricity and power of a network will follow the path of least resistance. In order to calculate the power of a resistive element, such as a resistor, at least two of three things need to be known: the resistance of the element, the voltage across the element and/or the current through the element. The power of an element can be calculated either by voltage times current; current squared times resistance; or voltage squared divided by resistance. Load The type of load attached to a network will affect a networks power flow as well. A resistor connected as a load to a network will generate a constant power flow. An electric motor will generate a very high power during startup due to the high current needed to start the motor. As the motor reaches its normal speed, the power needed will drop and stabilize to a fairly constant state. The power needed from the network will remain constant as long as the motor's speed and load are constant. If the motor's load increases, the power needed from the network will increase. Circuit Type There are two basic types of circuits, series and parallel circuits. In a series circuit, all of the current flows through one load. In a parallel circuit, there are multiple paths for the current to supply multiple loads. Each branch gets a fraction of the current depending on the resistance of each branch element. This also means that each branch will use a different amount of power.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
What is the total resistance if they have equal resistances in series in each of rows in parallel?
If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]
