Depends on the multimeter - this was a $10 multimeter so I'm assuming it will be within 10-20% of the true value. Nicer multimeters will be much more precise, as specified by their datasheets (which list their capabilities). Your cables will also affect the precision in a manner that is hard to predict, so if it feels "wiggly" then your precision will suffer.

Great video, but one correction for the tetrahedral crystal field splitting diagram is that g and u labels don't apply here (the groups are t2 and u only) because a tetrahedron has no inversion center. I often forget this when teaching it as well.
Good day Sir! what's your reference? Is it from a book? Thank youu for your response. Anyway, big thanks to your videos. It helped me in my Chemistry Lab.
That’s the point he’s trying to make right. No matter how u spin them, enantiomers are enantiomers. They can never be superimposed even though you rotate. Super impose means to overlap perfectly or simply, they are congruent or exactly the same object in dimensions. In general (not chemistry) if you mirrored a *symmetrical* object and rotated it, you *can superimpose* it. However if you take an *unsymmetrical* or *chiral object and rotated it about any axis you like however you try, then you can *never ever superimpose it* with In the video, Fe(en)2Cl2. When he rotates the compound, look the mirrored + rotated compound (the third one) and the previous compound (the first one), 😅notice the similarities:- 1) The central atom (Iron) 2) The chlorine ligand situated above the horizontal square plane or simply the top vertex of the octahedron 3) The diethyl amine ligand bonding with the iron in the same way and orientation in both compounds which is situated at the bottom right edge of the octahedron (it does of course tends to come out of the octahedron but to keep it simple, both are same). The above things *can be superimposed with each other* because they are exactly in the same position with respect to the central iron atom Now, notice the differences:- 1) The plane in the first compound consists of diethyl amine on the left side but the the plane of the third compound consists of the diethyl amine more like into the screen/plane/paper/negative Z axis or whatever u like. 2) The chlorine in the plane of both compounds is situated at different locations as well The above things discussed now, cannot be *superimposed* As observed till now, we can notice that the central atom(Iron) and two of the ligands(the ligands *non co-planar* ones or the ones situated on and below the plane) *can be super imposed perfectly* and two of them (the *co-planar* ones) are off and *can’t be super imposed*, we can finally conclude that the *complex on the whole, cannot be superimposed* though it is rotated I tried my best to explain this. I hope you understand.
Hi, great vid but I have a question. Where did you get the F table value of 5.820 (at 22:40min, when you are solving a practical problem for the F test)? I looked at your F table found at 11:54min, and I see value of 4.28 for two methods each with 6 degrees of freedom and within 95% agreement. Am I missing something? Thanks, in advance.
At the general chemistry level we'll either tell you how many ligands bond with the central atom or we'll provide you with simple rules (in my class I just tell students how many ligands there are, or make it known via chemical formula or name).
