compond angle formula and adding ac currents?
1. The problem statement, all variables and given/known data
two alternating currents I1 and I2 flow into a circuit node,the output current I is given by adding I1 and I 2.
find I and t, when I1 and I2 are as follows
2. Relevant equations
3. The attempt at a solution
i1=sin50t x cos 60 + sin60 x cos60t x by 1/2 gives
i1=2.5sin50t + 4.33 x cos50t
Hi guys help required on above question please not sure where this progresses
