Module overview

What this module covers

What it's about
This chapter covers the network theorems used to simplify and solve DC circuits containing dependent and independent sources: source transformation, superposition, Thevenin's theorem, Norton's theorem, and Maximum Power Transfer theorem.
Why it matters in exams
Finding the Thevenin/Norton equivalent of a given DC network, or verifying maximum power transfer, is the single most reliable numerical (Part B) question in this subject — it appears almost every semester and is worth practicing until it's automatic.
Think of it like…
Thevenin's theorem says: no matter how messy the network behind two terminals is, from the outside it behaves exactly like one battery and one resistor. You're not simplifying the circuit — you're proving the rest of the world can't tell the difference.
