Impedance 08
Impedance 08 : In reference to alternating electric current, the apparent resistance corresponding to the true resistance in direct current; a combination of inductive reactance and resistance is referred to as impedance. The symbol Z and the quantity is measured in ohms. There are two methods of determining the impedance of a circuit that is made of both inductive reactance and resistance. These are the vector or impedance triangle method and the computation method. (Load and resistance have relevance to fire cause)
