There are two circles here, one for a constant parallel resistance and a second for a constant reactance. The constant resistance line is symmetric around the x-axis. When the reactance is a near open ...

As with series circuits containing resistances, inductances, and capacitances, if the inductive reactance of a parallel circuit equals the capacitive reactance, the circuit is said to be resonant at ...

Q. What are the Code rules for the installation of single or parallel conductors in cable trays? See the answer below. A. To prevent unbalanced current in the parallel conductors due to inductive ...
