How does the total resistance in a system change when additional resistance is added in series?
Sneighke answered: This discussion adds to the original question There are two types of resistance topologies: 1) Series and 2) parallel. To answer your question, resistance added in series always ADD together increasing the total resistance of the circuit. Conversely, adding parallel resistance reduces the total resistance of the circuit. So, for series circuits, R(total) = R1+R2+...Rx Parallel circuits are the exact mathematical inverse. The easiest way to determine parallel resistance is to add the inverse of resistance which is conductance, conductance being 1/r and is stated in Siemens (hold the jokes!...), then taking the inverse of the total conductance to convert back into Ohms. For example, if you have three resistors R1, R2, and R3, and they are parallel connected, the total resistance of the circuit is the inverse of the sum of conductance which would be written as 1 / (1/r1+1/r2+1/r3). By definition, conductance is the inverse of resistance. An example: Given three resistors of 5, 100, and 500 Ohms, In series, R(total) = 5+100+500 = 605 Ohms. In parallel, the total is always less than the lowest resistor: Converting to conductance (used to be called Mhos which is "Ohm" backwards, but has been replaced with the SI unit of Siemens): 5, 100, and 500 Ohms = 1/5+1/100+1/500 = 0.200+0.010+0.002 = 0.212 Siemens. Converting back into resistance, 1/conductance = 1/0.212 Siemens = 4.717 Ohms which as stated above, is less than the lowest resistance resistor. In fact, sometimes working with conductance is easier in series/parallel circuits and, in particular, calculating which values of resistors are required to yield a desired resistance; usually a non-standard resistance value needed for a specific purpose in a circuit. An example: Say you need a non-standard resistance of 698 Ohms. Since we know that parallel resistors create a value lower than the lowest parallel connected resistor, you would start with the next highest standard value and then add a parallel resistor to get you what you need. In this case, you would subtract the desired conductance from the starting resistor: 698 Ohms = 1/698 = 0.001427 Siemens or 1.4327 milliSiemens. If we had a standard value resistor of 750 Ohms (remember, you have to start higher): 750 Ohms = 1.3333 mS. To find the required parallel resistor to get us our 698 Ohms, subtracting the conductances 1.4327mS-1.333mS = 99.33uS (micro Siemens) [0.00009933 S]. Converting back into Ohms, 1/99.33uS = 10.07kOhms (10,070 Ohms) which is close to the standard value of 10kOhms. Doublechecking, Add the conductances: 10,000 Ohms = 100uS 750 Ohms = 1.3333mS Adding gives a total conductance of 1.4333mS. Thus the parallel equivalent = 1/Siemens = 1/0.0014333 = 697.7 Ohms which is within 0.04% of the 698 Ohms we need which is well within acceptable error and we have our 698 Ohm resistor by connecting 10,000 Ohms and 750 Ohms in parallel.
Is ohms bigger unit to megohms?
An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What is the conductance of a wire that has a resistance of 400 ohms?
The conductance of a wire is the reciprocal of its resistance. Therefore, for a wire with a resistance of 400 ohms, the conductance would be 1/400 siemens, or 0.0025 siemens.
What is the conductance of a wire that has a resistance of 400ohms?
The conductance of a wire can be calculated by taking the reciprocal of its resistance. In this case, the conductance would be 1/400 ohms^-1, or 0.0025 Siemens.
How do you Convert mega ohms to micro siemens?
S = 1/R Where S = Conductance in Siemens R = Resistance in Ohms If R is in Mega Ohms, S will be in Micro Siemens
What is the difference between ohms and mohms?
ohms is the SI unit of resistance MHO (siemens) is the SI unit of reciprocal of resistance ie conductance
What is microsiemens?
A siemens is a unit of conductance or admittance, expressed as the reciprocal of resistance or impedance. (Siemens = 1/ohms) One microsiemens is 1 megohm.
The total resistance for this circuit if all resistors are 200 ohms is?
400 ohms
Is the unit of resistance and conductance are same?
The unit of resistance is ohms, the unit of conductance (1 / resistance) is siemens. 1/R = S, or alternately R = 1/S.
How much resistance must be connected in series with a 250 ohms inductive reactance to produce a total ciruit impedance of 400 ohms?
To find the resistance needed in series with the 250 ohms inductive reactance to give a total impedance of 400 ohms, we use the Pythagorean theorem for the impedance triangle in series circuits. Given the inductive reactance (X) = 250 ohms, total impedance (Z) = 400 ohms, and resistance (R) = unknown, we have R² + X² = Z². Substituting the values, we get R = √(Z² - X²) = √(400² - 250²) = √(160000 - 62500) = √97500 ≈ 312.5 ohms. Therefore, approximately 312.5 ohms of resistance should be connected in series with the 250 ohms inductive reactance to achieve a total circuit impedance of 400 ohms.
How do you convert micro ohms to siemens?
Ohm is the reciprocal of Siemens. Ohm = 1/Siemens.
What does Siemens measure?
Siemens measures electrical conductance. It is the dimensional reciprocal of Ohms. So if you measured resistance at 0.002 Ohms, the equivalent conductance is 500 Siemens. Note, this unit has been called mhos (Ohm spelled backward) as well. The symbol is an upside down greek upper-case omega character (just like Ohm uses a greek omega).
What is 500000 ohms per cm converted into micro siemens?
if I have seen this right, you are converting ohms to siemens? Check you conductivity (siemens), divide "1" by the conductivity value. in scientific notation 1000 would be 1x10^3 and change the units to ohms. If correct, you should have 5x10^5. May not have helped you.
How do you convert 123 milliohms to microsiemens?
Siemens is the reciprocal of ohm. You can convert from milliohms to ohms, then take the reciprocal. The answer will be in Siemens.
