Answer:
The approximate total impedance is 7.32ohms
Step-by-step explanation:
The formula for finding the phase angle between the current and source voltage of a simple AC circuit is derived from the relationship:
Cos θ = R/Z
From the formula we can get impedance Z given θ and R
θ is the angle of the total impedance
R is the resistance
Z is the total impedance
Given θ = 35°
R = 6ohms
Z =?
Cos 35° = 6/Z
Z = 6/cos35°
Z = 6/0.819
Z = 7.32ohms
