two electric devices A & B are connected in parallel and the rms current in A is 15 A. If the current in B lags behind A by pi/2 radians and the line current is 23.4 A. Determine the current in B

Best ResponseYou've already chosen the best response.1The line current is the resultant or the "total" In order to separate the total to the individual components, subtraction is the logical choice.

Best ResponseYou've already chosen the best response.0so that is the current in B?

Best ResponseYou've already chosen the best response.0another question, what is the difference between rms current and line current?

Best ResponseYou've already chosen the best response.1It is an inductive load when compared to the 15 amp load, or you could say the A is a capacitive load when compared to B. It is all relavent.

Best ResponseYou've already chosen the best response.1The line current is the combined currents of the two loads and is the current traveling to and fro from the power source. It is of course AC as we are talking RMS, all the currents in this problem is assumed to be measured in RMS units......including the line current.

Best ResponseYou've already chosen the best response.1Root Mean Square (RMS) is the most common value to measure AC, it is the value that DC current would produce as heat when the AC RMS value is converted to heat.

Best ResponseYou've already chosen the best response.1Kind of confusihng, but AC has several values of current/voltage. Peak Peak to Peak RMS (root mean square) Average

Best ResponseYou've already chosen the best response.0no. actually, my major is mechanical engineering, it's just that it's an elective course.

Best ResponseYou've already chosen the best response.1Not a degreed EE, but an EE as far as the U.S. Government, I was a GS855 for the FAA for years. There are other methods to become an engineer, but I recommend the method you are going, a formal education with a degree.
