To solve this problem it is necessary to use the concepts related to the Hall Effect and Drift velocity, that is, at the speed that an electron reaches due to a magnetic field.
The drift velocity is given by the equation:
Where
I = current
n = Number of free electrons
A = Cross-Section Area
q = charge of proton
Our values are given by,
The hall voltage is given by
Where
B= Magnetic field
n = number of free electrons
d = distance
e = charge of electron
Then using the formula and replacing,
The first one is Water
The second one is Juice
The third one Vinegar
The fourth one is Milk
The last one may be Shampoo
The 4 signifies the
atomic weight, and the 2 subscribes the element's
atomic number(aka the number of protons in the atom).
It's not possible to calculate the current with the given data. "Amp" is not a unit for measuring resistors, and "C" is not a unit for measuring batteries. So we don't know the resistance of this circuit or the potential difference applied to it, and thus can't calculate the current. If we could, it might turn out to be 3 gallons, but that's just a reckless guess.
