What is voltage difference?
Voltage at a point is defined as the work done by a unit positive charge carrying it from infinity to that point. while volage diffrance between two points is the work done bye unit positive charge from one point to the other point.work may be positive or negative depend upon the nature of charge that's why the potential will be negative or positive .CommentBy definition, voltage means potential difference. For this reason, you cannot have 'a voltage at a point' because potential difference, or voltage, exists between two points. You can, however, have a potential at a point.
What you do to obtain perfect dc output with no ripple?
This can only be done using a voltage regulator.
Why is a high voltage test conducted on wiring?
High voltage tests are done usually at the request of electrical engineers. When conductors are pulled into a conduit system, it is supposed to be done very carefully. In some instances this can not be done with out subjecting the conductors to mechanical stress. A high voltage test is applied to these conductors to make sure that the insulation factor of the wire has not been compromised. If the conductors do not pass the test, they have to be removed and new wire reinstalled.
Meaning of recovery voltage?
AnswerThe pressure that pushes the currentAnswer from University Physics Ed 11Voltage is the potential Vab of a with respect to b, which equals the work done by the electric force when a unit charge moves from a to b.1 Volt = 1 joule/column b
How do you find primary number of turns in a transformer?
Unfortunately, it is not practical to find the number of turns in a transformer's windings. However, what matters is its turns ratio. This can be done by applying a low AC voltage to the higher-voltage* winding, and measuring the resulting voltage appearing across the lower-voltage winding. The turns ratio will be approximately the same as the voltage ratio.(*NOT THE OTHER WAY AROUND! Or you may up with a dangerously-high voltage induced into the higher-voltage winding!)
How do I properly add freon to my home AC unit?
Adding freon to your home AC unit should be done by a professional HVAC technician. It is important to have the proper equipment and training to handle refrigerants safely. Attempting to add freon yourself can be dangerous and may result in damage to your unit or harm to yourself. Contact a licensed HVAC technician to properly add freon to your AC unit.
How can I tell if my residential hvac is under warranty?
Call the Hvac company to check if you have a current warranty.Keep warranty information in a folder with the unit. This way you will know when to schedule service and what was done.
What is a potential difference and what SI unit is used to measure it?
it is a quantity defined as work done per unit charge.it has same unit as voltage which is volt represented by 'V'.
When measuring resistance what should done to the supply voltage?
supply should be off
What is the unit for potentional difference?
Voltage (V) is the unit of p.d,The voltage itself s the difference in electric potentiel between two different points.It Just means the work done per unit charge can also be expressed as J C-1
Should I attend hvac online training for my education?
I've done quite some research on hvac, and yes. It is a professional company with high standards and is great for educational needs. You can also try rating's sites.
How can I check the refrigerant level in my AC unit?
To check the refrigerant level in your AC unit, you will need to hire a professional HVAC technician. They have the tools and expertise to properly measure and adjust the refrigerant levels in your system. It is important to have this done by a professional to ensure the proper functioning and efficiency of your AC unit.
In what way does voltage help us?
Necessity ( or say function ) of voltage can be understood by the definition of voltage: Work required to be done ( or energy needed ) to move unit positive charge ( or electron ) from one point to another in the circuit is called voltage or the potential difference. Hence, it can be said that voltage helps in flow of current.
Which unit should you use to measure the weight of a peanut?
the measurement of the peanut should be done in milligrams. but one would have to to give the answer in the SI unit which in this case would be kg.
Is there a procedure to convert a ac unit from r22 freon to 410?
It can be done. You probably don't have the qualifications to do it on your own, however. You'll need the services of an HVAC technician, for ease of the conversion, getting it done right, and also for your own safety, as handling refrigerants can be a bit on the risky side.
What size heat pump do you need for 2632 suare foot single story home with a 700 square foot room in the basement in northeastern Pennsylvania?
This question depends on alot of things. You should find a reliable HVAC company to run a manual j (sizing of hvac equipment) load calculation on your home. there are so many things that take part in sizing an a/c unit that if not done propperly than you could serious problems.
What is the unit for work done?
The unit for work done is the joule (J).
