    [/PLAIN] should t=.5 seconds?

    What is the Time Relationship of Alternating Current and Maximum Values?

    Oh okay, thanks. hmm.. for the second one... should the equation look like this..? CURRENT = 42.42 amps * sin ( 2 * pi * F * 0.0015) ? I am not sure on how to get the answer for B

    What is the Time Relationship of Alternating Current and Maximum Values?

    I got 0.0025004829... is that correct for t?

    What is the Time Relationship of Alternating Current and Maximum Values?

    30 amps = 42.42 amps * sin ( 2 * pi * F * t) so would it be sin-1(2*3.14*50*0)= 42.42 amps - 30 amps?

    What is the Time Relationship of Alternating Current and Maximum Values?

    Homework Statement A 50 cycle alternating current has a maximum value of 42.42A . It crosses the time axis in a positive direction when time is zero. Determine (a) the time when current first reach a value of 30 A. (b) time when current after having gone through its positive maximum value.
