SUMMARY
The impedance across a resistor is equivalent to its resistance value, such as 50 ohms for a 50-ohm resistor. In audio and radio technology, it is standard to refer to pure resistance as "impedance." However, real-world resistors may exhibit additional reactance, which can affect their performance in specific applications, such as using a wirewound resistor as an RF dummy load due to excessive inductance.
