Hi,
Sorry, I have to ask for the third time. My problem this time have to do with parallel RL circuits and impedance magnitude. Here is my attempt on the question:
"R=8200 Ohms, L=29 mH & e is a 240 V, 23Hz power supply. What is the magnitude of the impedance of the circuit?"
The solution:
6.28x29x23=4190.8846 ohms
( 8200 x 4190.8846 ) / [ ( 8200^2 + 4190.8846^2 ) ]^0.5=63657
This is one of the questions that was given to me at the practice problems section of the book and it gives me the answer 3732 Ohms. However, I got a different answer. How can I really get 3732 Ohms in a parallel RL circuit? Thanks.
