Module 5: Network theorems

Useful Equations

Superposition: $$\text{ Deactivate the voltage source}\to \text{short circuit}$$ $$\text{ Deactivate the current source}\to \text{open circuit}$$

Thévenin’s Theorem: $$R_{Th}\text{ all source to zero, }{E}_{Th}\text{ open-circuit terminal voltage}$$

Norton’s Theorem: $$R_N\text{ all source to zero, }{I}_N\text{ short-circuit terminal current}$$

Maximum Power Transfer Theorem: $$Z_L=Z_{Th}^{\ast }=Z_N^{\ast }\text{ , }{P}_{max}=\frac{E_{Th}^2}{4R_{Th}}=\frac{I_N^2{R}_N}{4}$$
