The expression which gives the magnitude of EMF generated in a DC generator is called EMF equation of DC generator. We shall now drive the expression for the EMF induced in a DC generator.Let,ϕϕ = flux per pole P = number of poles in the generator Z = no.of armature coductors ...
An alternator or a synchronous generator is a device used to convert mechanical energy to Alternating current electric current. The EMF equation of an alternator is a mathematical expression to calculate the effective value of EMF induced in each phase of an alternator or a synchronous generator. A...
EMF Equation of DC Machine TheDC machine e.m.fcan be defined as when the armature in the dc machine rotates, the voltage can be generated within the coils. In a generator, the e.m.f of rotation can be called the generated emf, and Er=Eg. In the motor, the emf of rotation can b...

EMF equation The electromotive force of the electrochemical cell can be calculated using the equation: EMFcell [V] = Ecathode [V] - Eanode [V] where Ecathode is the potential of the cathode (in volts) and Eanode is the potential of the anode (in volts). Remember that in a cell, th...
In this equation, N = 1 and the flux Φ = BA cos θ. We have θ = 0º and cos θ = 1, since B is perpendicular to A . Now ΔΦ =Δ(BA) = BΔA, since B is uniform. Note that the area swept out by the rod is ΔA = ℓΔx. Entering these quantities into the ...

Limit of Current: In the equation V = E – Ir if the magnitude of I or r is very high then the magnitude of V becomes very small. If Ir becomes equal to E, then V = 0 . Thus the cell cannot produce any potential difference in the external circuit. So, for every cell I has ...
