OK. I hope this question is acceptable here.
I am studying to take my Ham Radio License Technician's Class exam and I am not sure about the topic of load impedance and load in general.
I looked up "Load impedance" on wikipedia, I'm confused
This sentence "when a high power appliance switches on, it dramatically reduces load impedance" , I can relate to this sentece. When a table saw is switched on in my home, I can hear the lights flicker. Not sure if a "flourescent" is the same as "incandescent" in terms of being affected by this effect but I hear the flourescent bulbs respond.
Another sentence I don't understand is "If the load impedance is not very much higher than the power supply impedance, the voltage will drop"
From what I picked up in my Physics II class (E&M) there is a general relationship that as current increases, voltage decreases not sure if that is only a specific case not a generalization such as the case of a capacitor but...
I don't understand... can someone dumb it down for me?
I think of a power outlet as an open pipe that constantly pours out water and the load could be a straight pipe connected to the original pipe vs. a pipe that is more complex / presents "load" by friction or attempting to oppose gravity such as an inclined pipe.
I hope my question can be understood and answered properly.
If this question is in the wrong place, I'd appreciate it if it was moved to the appropriate location or I was told to move it and I'll do it rather than delete it.
Thanks
