WebJun 11, 2024 · Calculate the instantaneous value at 60° , average value and RMS value of an alternating current whose peak value is 20 A. asked Aug 20, 2024 in Electromagnetic Induction and Alternating Current by Suman01 (49.7k points) electromagnetic induction; alternating current; class-12; 0 votes. WebSep 30, 2024 · Hence, when the whole voltage or emf exists for short time interval in each emf cycle, there will be The higtest peak emf. Thus the two important factors in which peak value of alternating emf depends are: The percentage of each voltage half cycle in which the voltage value contributes to the effective value. The smoothness of the voltage waveform.
The peak value of an alternating emf E given by $E = {E_0 …
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. WebPeak value is defined as the maximum value reached by an alternating quantity in one cycle is known as Peak value. What is meant by avarage value? The average of all the instantaneous values of an alternating … thalasso centre france

WebWhat is the approximate peak value of an alternating current producing four times the heat produced per second by a steady current of \( 2 \mathrm{~A} \) in ... WebThe peak value is the maximum value of one alternation; the peak-to-peak value is twice the maximum or peak value. Q25. How many times is the maximum or peak value of emf or current reached during one cycle of AC? A25. Twice. Q26. If any point on a sine wave is selected at random and the value of the current or voltage is measured at that one ...
