What is the electromotive force?Components of an Electric CircuitAn electric circuit is the combination of electrical components to form a path for the electrons to flow. A simple circuit consists of a source that is connected to a resistor or a bulb. The flow of the electron in the circuit...
Why is it a law and not a theory? What is Faraday's first law of electromagnetic induction? What is tangential law? For what is it applicable? Define Ohm's law. What is the electromotive force? What is Coulomb's law? Explain briefly. ...
27 The electromotive force ( e.m. f.) of a rechargeable battery is 6.0 V.What does this mean? C A 6.0 J is the maximum energy the battery can provide in 1.0s. B 6.0J is the total energy the battery can provide before it has to be recharged. C 6.0J of energy is provided by ...
场强为零,电势不一定为零,因为电势是个相对量 The electric potential is, with the gravitational potential energy which relative says is same, does not have the frame of reference has no way to say its potential energy is how many. Likewise does not select a zero potential spot, is does not ...
Determine the mmf of the electromagnet. Solution − MMF = NI = 1500 × 2 = 3000 ATNumerical Example (2) A magnetic flux density of 1.6 Wb/m2 is required in the air gap of 4 mm. Calculate the mmf required. Solution −Magnetisingforce,H=Bμ0=1.64π×10−71.273×106AT/mMagnet...
In measuring electromotive force with a voltmeter, we should see to it that the voltmeter is placed in parallel with the electric source. 用伏特计测量电动势时, 务必使伏特计与电源并联。 I owe it to you that I am still alive. 幸亏你,我现在还活着。 有的语法学家把先行词it后的that从句看作...
When a conductor is placed in the changing magnetic field, the induced current in the conductor is termed as Eddy currents. Visit to learn its applications and more.
Electromagnetic Induction is a current produced because of voltage production due to a changing magnetic field. Check the formula and definition of electromagnetic induction by visiting BYJU'S
It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.What...
What is the concept of motional emf? A a motional EMF is anelectromotive force (EMF) induced by motion relative to a magnetic field B. An electromotive force (EMF) induced by motion relative to a magnetic field B is called a motional EMF. You might have noticed that motional EMF is very...
