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...
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.
What unit is used to measure current? What is electromotive force? What is the SI unit for reactance? What is a nominal current? What is the unit of electric charge? Define what a joule is. What is the unit of electrical resistance?
a因为我的听说能力比较弱 Because I heard ability quite is weak[translate] a你当时看的是这个形状的 You at that time looked were this shape[translate] apointed to by s1 指向由s1[translate] a电势是相对而言的,就跟重力势能一样,没有参照物是没法说出它的势能是多少。 同理不选取一个零电势点,是...
The Magnetomotive force (MMF) is defined as the work done in moving a unit magnetic pole once around the magnetic circuit. It is a magnetic pressure that tends to set up magnetic flux in a magnetic circuit. Mathematically, the mmf is the product of current and number of turns of a coil...
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
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 ...
What is a volt? A "volt" is a unit of electric potential, also known as electromotive force, and represents "the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt."[1]Sta...
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...
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...
