Does a Thevenin Equivalent Circuit Accurately Predict Power in Variable Loads?

[_wolfgang_]

In a thevenin equivalent circuit are you able to find the power used in the circuit by the variable load?
I have a circuit where the variable load is in parrallel I was thinking the power used in the original circuit by the variable load would be different than in the equivalent because it is in series.. Any ideas?

It's called the Thevinin Equivalent because its equivalent and it's purpose is to do exactly what you mention with it, that is convert a messy / complicated / busy circuit to a simple one so you can figure out some end result.

Why not try both ways and see for yourself!
