Best ResponseYou've already chosen the best response.0This is the definition of RMS current. RMS or effective value of a current is by definition such that the heating effect is the same for equal values of alternating or directcurrent. Here the ac current's max value is 2.60 A Can you find the rms value of this current ?

Best ResponseYou've already chosen the best response.1That is I rms with the formula: I rms = Imax/(sqrt(2)) So I rms = Imax/(sqrt(2)) I rms = 2.60 /1.4142 I rms = 1.838 A
