When measuring resistance should there be a voltage applied to the resistor?
No, the meter used to make the measurement will be applying whatever voltage to the resistor it needs to make the measurement. Any additional voltage will disturb this, resulting in at least an incorrect reading and at worst damaging or destroying the meter.
What is self resistance?
Self resistance is exactly what it sounds like it would be. It is the resistance that you make happen on your own.
Why does an ammeter have a low resistance while a voltmeter has high resistance?
I am going to assume that you mean low "resistance" in an open circuit test and are performing this with a multimeter. An ammeter works by place a very small amount of resistance in series with a circuit and then measuring the Voltage drop across the resistance. The Voltage is directly proportional to the current as given in ohms law: E = I x R If you are measuring the resistance through the ammeter it will have a very low resistance and impedance.
Why do you measure the winding resistance with a multimeter?
Actually, measuring winding resistance with a multimeter is an iffy situation at best. This is because the multimeter will not tell you if one of the turns is shorted, causing Q to drastically suffer, it will really only tell you if the winding is open, or if it is shorted to something it should not be shorted to, such as the frame. This is especially true for larger windings, in larger transformers and motors, because their DC resistance is so close to zero that you might not be able to tell if they are shorted or normal. Using a multimeter is a good start, to make sure that basics are covered, and it might tell you if the winding is dead shorted, but you need to know for sure what the expected DC resistance is, and you need to know that you multimeter is very good in the low Ohms scale.
What is auxiliary supply?
this type of supply use in satrter, it is a supply, when we are disconnecting our main supply ,it continue oue operation for few time. that means a way is make for the supply of our operations

What is mix c20?
C : refer to concret 20 : its Resistance of concret cube when we make test on it after 28 days measuring by N/mm2.
Should all the materials that make up a circuit have high resistance?
No. There should be substantial resistance only where the circuit design needs it and wants it, and as little as possible everywhere else in the circuit.
Why you use load resistance in any electronics circuit?
I think it is to determine how powerful you have to make your power supply to run the current demand load continously with a margin for error on the plus side. A 12 volt car battery has a low load resistance and needs some heafty components in a battery charger. A charger (or supply) for a 12 volt boom box with a high load resistance may be the size of a small paper cup. They both supply 12-15 volts but the load resistance is very much different E=IR I=E/r R=E/i
What type of supply should you not use hemp to make a seal?
this question makes no sense
Why should you put the meter on the negative side when measuring current?
A meter can be used both on the positive or negative side of a circuit when measuring current. The current going to a load should be equal to the current coming back from the load. When measuring DC current, make sure the meter should be more than adequete to be placed in series with the circuit. Otherwise, use a clamp-on meter.
If your rough in plumbing is not aligned with the sink drain what should you use to make the connection?
Most P traps and waste elbows allow enough play to make them work. But if alignment is to far out and you don't want to go but in and make corrections they do make flexible tailpieces that should work. If it's your supply fittings they make a varity of different length supply lines.
How can you make the resistance higher in a circuit?
A: practically any series resistance will do that
What is self resistance?
Self resistance is exactly what it sounds like it would be. It is the resistance that you make happen on your own.
How do you measure 16.3 ounce peanut butter with measuring cup?
Measuring peanut butter is easy. When measuring peanut butter you have to make sure the measuring cup is setting down.
How should I measure my child to make sure the sleeves on the Dickie long-sleeved stretch shirt will fit?
You should use a measuring tape and measure the arm length and width.
