How was Ohm's law ever verified?
To verify it you need to measure the current, voltage and resistance over a range of values and show that ohms law satisfies their solution. The catch is that typical ohmmeters do not measure resistance, they measure current and voltage and use ohm's law to find the resistance. If you use an ohmmeter to verify ohms law then you are assuming ohms law is true in order to show that it is true which is logically flawed.
