A series circuit contains R = 150 Ω, and C = 10uf, and connected to a 110 volt source. If the source frequency is 120Hz , find the current flowing through R.
The answer seems to says it was 0.55A
SOLUTION:
Xc = 1/(2pifC) = 132.63 Ω
Z = √(150^2 + 132.63^2)
Z = 200.23 Ω
I = V/Z = 110/200.23 = 0.5494A
θ = arctan(- 132.63/150)
θ = -41.48
Rec(0.5494 < -41.48)
0.5494 = 0.4116 - 0.3638998j
where Ir = 0.4116 ===> does not = to the answer key given
