Question

Can you have a negative impedance$?$

Answer 1

Impedance: Impedance is the result of combining resistance and reactance. It's basically anything that prevents electrons from flowing freely via an electrical circuit. As a result, it has an impact on the current generation in the electrical circuit. Impedance is represented mathematically by the letter $Z$,

$Z=\sqrt{R^2+{\left(X_L-X_c\right)}^2}$

Where $Z$ is the impedance

$R$ is the resistance

$X_L$is the inductive reactance

$X_C$ is the capacitive reactance

Capacitors will have negative impedance based on the behavior in the circuit,

Therefore it is possible to have a negative impedance.
