Ch. V/R = I
V = voltage R = resistance I = current
New: Voltage is like a faucet = total charge supply / time
Total charge/time (V) / resistance (R) = charge through
resistance / time (I)
6.14 Brightness measurement distance
Efficiency is brightness/energy input
The longer the distance, the less the measured brightness, the
darker the light, the more the light spreads out. The shorter the
distance, the higher the brightness. So you need to measure the
distance. Many people do not include measurement distances in
efficiency papers.
6.15 Electronic model is not trusted
Why aren't electrons attracted , pulled, and hit Core neutrons
and protons? Use nucleus to stimulate or guess electrons
movement model.
May it be gravity rather than charge pulling?
The electronic model may not be reasonable.
6.16 in quantum physics
1. Inside quantum physics
2. Why is the wave function ^ 2 = probability of electrons? No
reason.
6.17. Fluid mechanics
In fluid mechanics, the Navier Stokes equation proves to be
wrong.
6.18 Circuit Design Related
1. Confusion occurs when the voltage direction is opposite to
the current direction.
2. If there is no ground voltage and the current direction is
unknown, an error will occur.
