How do you determine if a circuit element is absorbing or supplying
power?

Ans: Define the current and voltage to satisfy the passive sign
convention. V*I, if positive absorbed, if negative supplied


Thevenin's theorem (as studied to date) with all qualifications to when
it does and does not apply

Ans: Any linear resistive circuit is equivalent at its terminals to
the series combination of an ideal voltage source and a resistor
(Thevenin resistance)


Norton's theorem (as studied to date) with all qualifications to when it
does and does not apply

Ans: Any linear resistive circuit is equivalent at its terminals to
the parallel combination of an ideal current source and a
resistor (Thevenin resistance)


Superposition theorem (as studied to date)

Ans: In any linear resistive circuit, we can find any voltage or
current in the circuit by summing the corresponding voltages or
currents that are caused by each independent source acting
separately. NOTE: to kill a voltage source, it becomes a short,
to kill a current source, it becomes an open circuit. Never kill a
dependent source. Also, one cannot sum powers due to each
source to get the total power, because power is a nonlinear
function of current and voltage.
