What is the EMF equation of alternator?
EMF equation of DC GeneratorE = (ΦNPZ) / (60 * A)where,E = e.m.f induced in any parallel path in armatureΦ = flux per pole in weberN = armature rotation in revolutions per minute (r.p.m)P = No.of generator polesZ = total number of armature conductorsA = No.of parallel paths in armature
How emf induce while apply in primary side of the transformer?
when an alternating current apply on primary side of transformer then magnetic flux produced in the iron core of transformer.Then flux link with secondary winding of transformer so that an emf produced in a transformer.
What is emf equation of synchronous reluctance motor?
The electromotive force (EMF) equation of a synchronous reluctance motor can be expressed as ( E = 4.44 \times f \times \Phi \times T ), where ( E ) is the induced EMF, ( f ) is the frequency of the supply voltage, ( \Phi ) is the magnetic flux per pole, and ( T ) is the number of turns per phase winding. In synchronous reluctance motors, the EMF is generated due to the rotor's reluctance variation in the magnetic field, rather than traditional winding-induced EMF, which is typical in other motor types. The motor operates at synchronous speed determined by the supply frequency and number of poles, contributing to its efficiency and performance characteristics.

What is construction and working of single phase transformer?
The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1

What is the main cause for the coefficient of coupling of a transformer being less than unity?
initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
How do you rearrange the emf equation into a form suitable for plotting a straight graph?
To rearrange the electromotive force (emf) equation into a form suitable for plotting a straight graph, you typically isolate the dependent variable on one side. For example, if the equation is of the form ( E = IR + r ) (where ( E ) is emf, ( I ) is current, ( R ) is resistance, and ( r ) is internal resistance), you can rearrange it to ( I = \frac{E - r}{R} ). By plotting current ( I ) on the y-axis and the emf ( E ) on the x-axis, the slope of the resulting line will relate to the internal resistance and the resistance of the circuit.
