Homework Statement
Say you connect Circuit A with low output impedance to circuit B with high input impedance. Why does this cause minimal voltage drop compared to connecting them the other way around (high output to low input).
Homework Equations
P = V^2/R
P = IV
The Attempt at a Solution
I am guessing that the power must stay the same when going from circuit A to circuit B, so when the resistance increases, the voltage drops to keep the power equal. But why does this cause a "minimal" voltage drop. Wouldn't matching the impedance be the best way reduce the voltage drop?
