(1), that for any dc generator Z, P and A are constant so that Eg ∝ Nϕ. Therefore, for a given DC generator, the induced EMF in the armature is directly proportional to the flux per pole and speed of rotation.For a DC motor, magnitude of the back emf is given by the same emf equation of a dc generator i.e. Eb = PɸNZ / 60A. For a machine, P, Z and A are constant, therefore, N ∝ Eb/ɸ Page 13 Characteristics of DC shunt motors : In case of DC shunt motors, we can assume the field flux ɸ to be constant.electromotive force, abbreviation E or emf, energy per unit electric charge that is imparted by an energy source, such as an electric generator or a battery. Energy is converted from one form to another in the generator or battery as the device does work on the electric charge being transferred within itself.

What is equation of back emf?
Net voltage = supply voltage + back EMF
Back EMF = -45 V. Net voltage across the motor, calculated according to Ohm’s Law (V = I x R = 10 A x 15 Ω), = 150 V.
How do you calculate emf of a generator?
We use Faraday’s law of induction to find the average emf induced over a time Δt: emf=−NΔΦΔt emf = − N Δ Φ Δ t . We know that N = 200 and Δt = 15.0 ms, and so we must determine the change in flux ΔΦ to find emf.
What is emf equation of transformer?
emf = turns x rate of change
This is known as the Transformer EMF Equation. For the primary winding emf, N will be the number of primary turns, ( NP ) and for the secondary winding emf, N will be the number of secondary turns, ( NS ).

What is a transformer explain its working principle and derive its EMF equation?
Working Principle of a transformer
The induced emf in the primary winding is nearly equal and opposite to the applied voltage V1. Assuming leakage flux to be negligible, almost the flux produced in primary winding links with the secondary winding. Hence, an emf e2 is induced in the secondary winding. e2 = −N2dφdt.

What is induced EMF in transformer?
Magnitude of the induced EMF (or Voltage) in a transformer can be found by EMF equation of the transformer. When a source of alternating current (AC) is applied to the primary winding of the transformer which is known as magnetizing current, it produces alternating flux in the core of a transformer.
How is emf formed?
Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.
