For capacitors and inductors, the following will help your understanding, I hope:
caps: The voltage across a capacitor CANNOT change instantaneously.
inductors: The current through an inductor CANNOT change instantaneously.
Ohms LAW: R = V/I is only valid for RESISTIVE CIRCUITS. I will rephrase that to mean that the voltage and the current are in phase. Variations exist such as P=V*I*cos(theta) for SOME AC circuits. It's true for DC because cos(0) = 1.
Most AC voltmeters read the correct AC voltage for sine waves. True RMS voltmeters will have restrictions.
The RMS (Root Mean Square, a calculus term) value of a periodic waveform would be the same DC value that would produce the same power.
Current and electrons flow in different directions. What we normally use is what's called "conventional current". Ben Franklin got the sign wrong and it hasn't been fixed. So, to help us visualize semiconductors, "Hole flow"="conventional current" was invented.
Power disipated is positive. Power generated is negative. But, we never say we have a -10 MW electric plant. In analysys WE know to flip the sign.
Insertion of current meters generally disturb the circuit.
Accuracy and precision of numbers matter. I've had instances where 2E16 and 5e16 were considered the same number. It would be a big difference if it were money.
These are some of the STUPID things that I was never told initially.
AC, DC and 3 phase are very different animals. Similarly I learned in chemistry that there were circular orbits. Later I learned that these are not circular, but rather probablility distributions.
I also took computer courses and I "got the wrong answer", because I wasn't supposed to have the knowledge of the right answer. I argued my way out. You have to answer questions based on what your "supposed" to know.
I can ask: "paper conducts electricity" T/F. I can say T and prove it, but the expected answer is F. Now if I said, "paper is an insulator (T/F)". Again I could pick any answer and argue either way. or "Is air an insulator?". I can argue that too both ways. CONTEXT makes a BIG difference. Basically, there isn't enough information in all of these questions to answer them properly.
I'll leave you with a question: "How do you know what wire to buy"?
