To convert volts per ohm to microamps, the correct approach involves multiplying by 1,000,000 (10^6). For example, a calculation of 2.7 V/Ohm results in 2,700,000 microamps (uA). The relationship between voltage (V), current (I), and resistance (R) is defined by Ohm's Law, where 1 Amp equals 1 Volt per 1 Ohm. Therefore, understanding this conversion is crucial for accurate electrical measurements. The discussion emphasizes the importance of proper unit conversion in electrical calculations.

conversion for volt/ohms to uA

is it 10^-6?
I just want to make sure, thanks!

Well you multiply by 10⁶, right? So 2.7 V/Ohm = 2700000 uA.

But yeah, because V = IR, an Amp is a Volt per Ohm.

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
