The next question: If you have a good power conditioner, how much does the power cable matter then?
Axle thanks for the info, 0 impedance is clear ,but i do not understand the power factor.
Hi Robert,
Power factor is a measure of efficiency. It is the ratio of real power to apparent power expreassed as a ratio between 0 and 1. It quantifies how well voltage and current work together. If voltage and current are perfectly aligned, that is a power factor of 1. If they are prefectly misaligned, that is a power factor of 0.
An analogy of low power factor is how well a car's motor and transmission work together. If you are trying to go top speed in 1st gear, the motor strains and works really hard, but you can never gain much speed. Similarly, with low power factor, your amp may work very hard but may not perform well.
A cable can increase power factor by impedance matching.
