Nettet5. sep. 2024 · The emf induced is given as e=NBA e=50×(2×10 −5×sin(10πt)) Time period is T= 51=0.2sec The emf induced in one full cycle is zero. So the maximum emf induced will be in half cycle e= 0∫0.110 −3sin(10πt) Hence, the maximum induced emf is 2×10 −3.

NettetE = 4.44fϕmN ⋅ ⋅ ⋅ (6) Equation (6) is known as EMF equation of a transformer. For a given transformer, if we divide the EMF equation by the supply frequency, we get, E f = 4.44ϕmN = Constant. Which means the induced EMF per unit frequency is constant but it is not same on both primary and secondary side of the given transformer. Nettet5. nov. 2024 · Determine the emf induced in the loop as a function of time. 32. The magnetic field perpendicular to a single wire loop of diameter 10.0 cm decreases from 0.50 T to zero.
