Thats some funny stuff righ there! A load is a load!!! Man some people need to lay off the pipe :shock:
There are times when "a load is a load" is just not quite correct.There is a differance in efficiency when the load is purely resistive or when it is inductive.Most highly inductive loads have a power factor corrector built into them which is basically some value of capacitors that helps tp improve the overall efficiency of the device.I had an FM transmitter that would run about 8% worse in eff. when the power factor corrector capacitors were disconnected from the AC line.I had to disconnect them because,for some reason that no one could explain other than it happens sometimes,the backup generator did strange things to the transmitter.The transistor had several switching type power supplies.
