Hi!
I wanted to know what these phrases mean in the context of voltage/current-
A) 'hard to drive' - does it mean it requires more current or more voltage (they are proportional acc. to Ohm's law but what does it usually refer to) ?
B) 'loading a circuit'- what does this mean.. when one circuit is connected to another, and if the second circuit loads the first one, does it mean it causes a high voltage drop across itself, and when this happens does it mean the second circuit has a high impedance/resistance?
Thanks in advance.
