I 12 v600 ohm i 002 a 20 ma milli ampere so the current in the circuit is 20 ma if you dont like calculating things yourself check out this calculator for ohms law another example let us try another example below we have a circuit with a resistor and a battery again but this time we dont know the voltage of the battery.
carbon14 dating can be used on objects ranging from a few hundred years old to 50000 years old heres an example of calculating carbon14 dating.
No ohms law is not being cheated here shorting a voltage source with a 0 ω conductor will not result in infinite current because there are other sources of resistance in such a circuit the task here is to determine where those sources might.
carbon14 dating is something that you hear about in the news all the time find out how carbon14 dating works and why carbon14 dating is so accurate.
