Voltage:

- Measure of electrical energy

- Measure of difference in polarity 

 

▲ Currents that the flow when it has a conductive path (wires)

*Resistance: Opposition to the flow

*Impedance (Z) is Audio Resistance (Ohm)

 

*In Speaker circuit: Resistance doesn’t impact on frequency. However, Coils mainly impact on frequency.
