What is the resistance scale on an analog multimeter often termed?
Resistance is measured in ohms, so some refer to the resistance scale as the ohms scale.
How do you find voltage rating of zener diode?
It should be marked, either on the diode or on the box it came in. If you can't find the mark, then you have to measure it yourself. Take the zener diode, a battery or DC power supply, and a resistor. Wire them all in series, with the NEG (cathode) end of the diode closer to the POSitive side of the battery or power supply. Connect your voltmeter across the diode, and slowlyincrease the power supply output voltage while watching the meter. You'll see the voltage across the diode increase slowly, tracking the power supply, until you reach the Zener voltage. At that point, the voltage across the diode won't increase any more; it'll just stay there at its 'reverse breakdown' voltage, which is the Zener voltage. (If the voltage across the diode goes to around a volt and won't go any higher, the polarity is wrong. Reverse either the diode or else the power supply.) You probably want a wild guess at what the value of the resistor should be. That's difficult to specify if I don't know the power rating of the Zener diode you're testing. I'm going to make the following suggestion completely in the blind: Select the resistor to limit the series current to 30 mA even if you have to crank the power supply up to 50 volts. R = 50/.03 = 1.5 to 2 K-ohms, rated for a couple of watts.
How many pennies are in 100 dollars?
There are 100 pennies in 1 dollar then there would be 10,000,000 pennies in one million dollars. 1 million = 1,000,000. Instead of penny say cent. Cent is the correct word for 1/100 of a dollar.
Why is 100 weight abbreviated to cwt?
Cwt stands for centium weight. The 'wt' in 'cwt' is obviously the abbreviation of 'weight'. The 'c' in 'cwt' probably refers to the Roman numeral for the number 100. Hence, C wt is read at 100 weight.

What is the conductance of a 10 ohm's resistor?
Conductance is the reciprocal of resistance, and is measured in siemens (S). So a 5.1 ohm resistor has 1/5.1 conductance, which is approximately 0.196 078 431 372 549 019 607 843 137 254 9 S.
How do you determine shorted resistor?
A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
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.
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.

Definition for tolerance value of a resistor?
An allowable amount of variation on either side of specified measure. If a resistor is labelled as 100 ohms, with 20% tolerance, it might be anywhere from 80 to 120 ohms. If a resistor is labelled as 100 ohms with 10% tolerance, it should range between 90 and 110 ohms. If a resistor is labelled 100 ohm with 5% tolerance, it could vary between 95 and 105 ohms. A tolerance is both ways, if a measure has 10% tolerance, then the total variation is 20%, plus 10 added to minus 10. If you are talking about variation to one side alone, the term is "deviation". If a resistor is supposed to be 100 ohms and actually tests at 105 ohms, it deviates by 5%, but is within allowable variation if it is specified to be within 5% tolerance.
When 10 ohm resistor and 100 mega ohm resistor are connected in series then what will be the combined resistance?
100 megohm the 10 ohms completely vanishes in the tolerance of the 100 megohm resistor, in that range tolerances can exceed 20% of nominal.
