Hiya
Aaaarghhh....
I'm probably having a face palm moment but am having a blank at the moment.
I know how to calculate basic voltage drops using ohm's law by calculating current flow first. But what do I do if current is a known fixed value?
If I have a module that uses e.g 275mA at a supply of 5V, if there is a resistance of 10ohm after the voltage regulator, what is the voltage drop across the resistor?
Cheers
