Superposition Theorem

• States that the response of a linear circuit to multiple sources is the sum of the responses to each source acting alone

Maximum Power Transfer Theorem

• States that maximum power is transferred to a load when the load impedance is the complex conjugate of the source impedance
• Used to optimize power transfer in circuits

Impedance and Admittance

• Impedance (Z): total opposition to current flow in a circuit, including resistance and reactance
• Admittance (Y): total ability of a circuit to conduct current, including conductance and susceptance
