PopCorn Dude Admin Posted August 6, 2021 Report Share Posted August 6, 2021 An alternating current, I amperes, is given by I =10sin 2π f t, where f is the frequency in hertz and t the time in seconds. Determine the rate of change of current when t=20ms, given that f =150Hz. Quote Link to comment Share on other sites More sharing options...
0 DrD Posted August 6, 2021 Report Share Posted August 6, 2021 What is the purpose for this question? This looks like a freshman physics pop quiz. Does the Admin really not know how to work this? DrD Quote Link to comment Share on other sites More sharing options...
