0.1 mhos
mhos = 1 / ohms
Another Answer'Conductance' is the reciprocal of resistance, and its SI unit of measurement is the siemens (symbol: S). The 'mho', its former unit, has not been used since the 1960s. So the answer is 0.1 S.Wiki User

What is the impedence?
Impedance is the complex form of resistance. Impedance takes into account capacitance and inductance in a circuit as well. Impedance can be represented as resistance as a function of frequency.See link.AnswerImpedance is not a 'complex form of resistance'. It is the vector sum of a circuit's resistance and reactance. In electrical engineering, 'resistance' has a very specific meaning, and cannot be used to denote 'opposition'.
What is RF current?
Measuring RF CurrentOnce again, our multimeter on AC scales fails at measuring radio-frequency sinewaves. Current measurement is a bit more difficult than voltage measurement shown above. We shall use the same peak-detector circuit, measuring the voltage drop across a small sampling resistor. This resistor will drop a small voltage as RF current flows through it. The peak detector will measure this voltage drop. Ideally, a very small sampling resistor is best: it must be much smaller than the 50 ohm load. If not, the combination of 50 ohm load and series sampling resistor will increase the load seen by the transmitter.If we were to use a one-ohm sampling resistor (1st circuit), the voltage available (for a 5W output) would be 0.447 peak volts. Not very much: errors due to diode-drop will be high, and even worse at lower power.Let's use a transformer to step up the available voltage going into the peak detector (2nd circuit). We'll use a 1:10 turns ratio on our transformer, and use a ferrite core to make sure all the flux links to every winding. If the ferrite has high enough permeability, the primary winding can be one turn, while the secondary winding can be ten turns. It needn't be a big core, since very little power is going into the peak detector.Rather than place a one-ohm resistor at the primary side, its better to add a 100-ohm resistor on the secondary side (3rd circuit). Since impedance is transformed by the turns-ratio-squared, the primary will still see a one ohm impedance. The diode measures the peak voltage across this 100-ohm resistor. Now instead of 0.447 volts peak, we'll get 4.47 volts peak - a substantial improvement in sensitivity.
How many lights off one switch?
ten lights per curcuitCircuit loadingIn Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.
How much is 10.2 kilo ohms?
10.2 kilo ohms is the resistance necessary for 1 volt to induce a current of 98.04 micro amperes. Ohm's law: voltage equals current times resistance.
What would the current draw be if there was six ten ohm resistors connected in series across a 120 volts?
The total current in a circuit consisting of six operating 100 watt lamps connected in parallel to a 120 volt source is 5 amperes. Since power is volts times amps, take 600 watts (100 times 6) and divide by 120 volts to get 5 amps.
Why resistance use in silicon diode characteristics?
Resistance is used in characterizing silicon diodes, or any component for that matter, because the equivalent resistance in a certain condition tells you what the circuit will do in that condition. It is true that a diode is not a resistor, but it has an equivalent resistance at each point on it operating curve. Let take three points, for example... With one ampere of current, the forward voltage might be 0.68 volts. That corresponds, using Ohm's law, to a resistance of 0.68 ohms. With ten amperes of current, the forward voltage might be 1.15 volts. That corresponds to a resistance of 0.115 ohms. With 25 amperes of current, the forward voltage might be 1.7 voltage. That corresponds to a resistance of 0.068 ohms. You can obtain the forward resistance curve from the manufacturer's data sheet. Even if there is only a voltage versus current curve, you can calculate resistance using Ohm's law. You need to know the resistance curve in order to design the circuit that uses the diode. In high performance situations, such as in large power supplies, the resistance of the diode may well be critical, and would therefore be a factor in selecting which diode amongst several choices to choose.
How many ohms is in 10k ohm?
Ten thousand (10,000).
True or false ohm's law asserts that the current in a conducting wire is proportional to the resistance of the wire?
It's true, but only for a constant applied voltage. It turns out that the current in that wire is also proportional to the voltage applied to the circuit. Here's how it works.For a given applied voltage, current is (inversely) proportional to resistance. More resistance (for that same applied voltage) makes for less current will flow. Less resistance (for that same applied voltage) means more current will flow. We say that current and resistance are proportional because for a given voltage, when one goes up by "X" amount, the other goes down by the same proportion. Double the resistance, current is cut in half. Ten times the resistance will allow only one tenth the current. And we say inversely, because the change is in the "other" direction. When current goes up, resistance must have gone down (for that same applied voltage). Here's the other half of the idea with current and voltage and a given value of resistance.In a circuit with a fixed resistance, more voltage will drive more current. Less voltage will drive less current. They're directly proportional. That means if you double the voltage, you'll get double the current (through the same resistor). If you cut the voltage by a factor or ten (one tenth the applied voltage), you'll end up reducing current by a factor of ten (one tenth the current) for that same resistor. We usually think of circuits this way, but we can also think of them in other ways according to Ohm's law. Let's summarize.Voltage (E) is expressed in volts (V), and current (I) is expressed in amps (A), and resistance (R) is expressed in ohms (upper case omega).E = I x R (E equals I times R)R = E / I (R equals E divided by I)I = E / R (I equals E divided by R)AnswerFalse. Ohm's Law, in essence, states that the ratio of voltage to current is constant for variations in voltage. No mention of resistance whatsoever! However, for those materials that obey Ohm's Law ('linear' or 'ohmic'), raising a conductor's resistance will cause the current to fall (assuming the voltage is fixed). so the current must be INVERSELY proportional (not proportional) to the resistance!
How do you restrict amperage delivery without restricting voltage - I want a device to recieve only half an amp at 240V - Maybe a variable device like a rheostat or potentiometer?
Ohms law states that in a series circuit voltages change at every device, while amperage remains constant . Whatever current is applied to a series loop, or leg of circuitry must pass through every point of that loop. However Ohms also says that voltages are constant while currents change in PARALLEL loops. If for example 240 volts are offered the chance to push current through two loops, one with say a 10 thousand ohm resistance, and the other loop with a one ohm resistance, most of the current will select the single ohm, for its ease of travel, but each connected complete loop will have the same 240 volts applied and a small current will flow through the ten thousand ohm resistance.( A shunt is an additional resistance applied, in a series or by adding an extra loop to separate current values. so research shunts). By the way,I before E except after C, remember?
What is the potential difference between the terminals of 10 ohms resistance which carries of current of 3 ampere?
Ohm's Law: Voltage is current time resistance3 amperes through ten ohms is 30 volts.Note: This is also 90 watts, enough power to generate heat. Resistance is a function of temperature, so things will change as the resistor gets hot.

Is 5000 ohm is high impedance?
Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
How do I read the electrical testers that I own?
The first step in reading your electrical tester is to determine what type of circuit you are testing and set the meter accordingly. Next you determine the suspected range of the circuit you are testing and set your meter to at least ten times that amount. The red wire is then connected to the positive connection and the black wire is connected to the negative or ground connection. You then read the number from the scale you are working with. For example, the red scale is for AC (houses) and the black scale is for DC currents (car, boat, or RV) Finally, you read the resistance by determining the Ohm reading on the very top scale of black numbers. The amps are determined the same way as voltage.
