WebSep 12, 2024 · Figure 13.7. 3: The emf of a generator is sent to a light bulb with the system of rings and brushes shown. The graph gives the emf of the generator as a function of time, where ϵ 0 is the peak emf. The period is T = 1 / f = 2 π / ω, where f is the frequency. The fact that the peak emf is ϵ 0 = N B A ω makes good sense. WebThe magnitude of the emf induced can be calculated with the help of the emf equation of the DC generator. The circulation of induced current takes place within the closed path. With the help of Fleming’s right-hand rule, the direction of the induced current can be determined.
