Magnetomotive force establishes magnetic flux in a magnetic circuit, which is opposed by the reluctance of that circuit. It's easy to relate these magnetic quantities to the equivalent quantities in an electric circuit:
- magnetomotive force is equivalent to electromotive force
- flux is equivalent to current
- reluctance is equivalent to resistance
A magnetomotive force (mmf) is created whenever an electric current passes through a coil. It's magnitude is determined by the product of the current (I) flowing through the coil and the number of turns (N): mmf = I N
The unit of measurement of magnetomotive force is the ampere. Although, to prevent it from being confused with the unit of measurement for current, it is usually spoken as "ampere turn".
What else can I help you with?
How do you calculate ampere given 220v AC 40KW?
The formula you are looking for is I = W/E
The opposition to magnetic flux as it flows through a magnetic circiut is?
The opposition to the formation (not 'flow') of magnetic flux is the ampere per weber (often spoken as 'ampere-turn per weber'). This is derived from dividing the magnetomotive force produced by a winding, expressed in amperes (often spoken as 'ampere-turns'), divided by the resulting magnetic flux. expressed in webers.
Who was ampere named after?
The ampere was named after André-Marie Ampère.
What is the charge flowing per second in a circuit?
The numerical representation of one coulomb of charge moving past a point in a circuit per second is called an ampere.
What is the abbreviation for ampere?
A
What is is the dimensional formula of electric current?
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
What is an ampere-turn?
An ampere-turn is the unit of magnetomotive force, calculated by multiplying the number of turns in a coil by the current flowing through it. It represents the strength of a magnetic field generated by an electric current in a coil.
How do you calculate ampere given 220v AC 40KW?
The formula you are looking for is I = W/E
What is the formula of total amps?
There is no 'formula' which defines the ampere. The ampere is defined in terms of the resulting force between two parallel, current-carrying, conductors, due to the magnetic fields surrounding those conductors.
What is the formula to get the ampere using a 12 volts?
To obtain amperage from a formula you need at least two components. Formula for amperage are I = W/E, I = E/R and I = sq root of W/R.
How many volts in 1 ampere?
That's like asking how many meters in a liter. Ampere and Volt are two DIFFERENT measurements. Ampere is how much electricity you are using, while volts are how much pressure the electricity is under(Think water). If you want to figure out how many amperes your appliance is using you could use this formula: P=UxI (Watt=Volt x Ampere) or U=RxI(Volt=Resistance x Ampere).
What is the name of unit of electric current in fps system?
ampere is the unit in all the systems for electric current
