Resistance vs Impedance What is impedance Impedance (Z) Â is similar to Resistance (R) . Impedance and Resistance both oppose the current in the circuit. Both are almost the same thing, But resistance related to DC Circuit. Resistance opposes the steady electric current in the DC circuit. Resistance remains the same (constant) at any different frequency […]
