In the particular “experimental brief” given to some students attending lessons here, internal resistance was to be determined using a “homemade” resistor of approximately ##\;4 \Omega## for the load. Measurements of open circuit voltage, terminal (load) voltage, and current were to be ma...
This function $$\frac{e^x - e^{-x}}{2}$$ is called the hyperbolic sine. I'll refer to it as "hypersine" for short. You could say it "splits the...
