Question: Given i 1 ( t ) = 2 0 4 cos ( t ) i 1 ( t ) = 2 0 4 cos (

Given i1(t)=204cos(t)i1(t)=204cos(t) A and i2(t)=134cos(t+30)i2(t)=134cos(t+30) A, use superposition to compute the current II.
Use 2 digits after the decimal point if necessary in your answers below.
a. What are the phasors for i1(t)i1(t)and i2(t)i2(t)in polar form (r)(r) with rr in Amps and in degrees?
I1=(r1)(1)=(I1=(r1)(1)=(Answer 1 Question 8A)(A)(Answer 2 Question 8))
(note: r1r1 is positive and11 can be positive or negative)
I2=(r2)(2)=(I2=(r2)(2)=(Answer 3 Question 8A)(A)(Answer 4 Question 8))
(note: r2r2 is positive and22 can be positive or negative)
b. What values (in Amps) must be summed to produce the final answer?
LetII be the contribution of current source I1I1:
I=(x1)+j(y1)=(I=(x1)+j(y1)=(Answer 5 Question 8)+j()+j(Answer 6 Question 8)A)A
(note: both x1x1 andy1y1 can be positive or negative)
LetII be the contribution of current sourceI2I2:
I=(x2)+j(y2)=(I=(x2)+j(y2)=(Answer 7 Question 8)+j()+j(Answer 8 Question 8)A)A
(note: both x2x2 andy2y2 can be positive or negative)
c. What is the final answer (in Amps)?
I=I+I=(x1+x2)+j(y1+y2)=(I=I+I=(x1+x2)+j(y1+y2)=(Answer 9 Question 8)+j()+j(Answer 10 Question 8)A)A
