Which theorem simplifies complex linear circuits to a single voltage source and series resistance?
- Kirchhoff's Law
- Thevenin's Theorem
- Norton's Theorem
- Both B and C
Answer: Both B and C
Thevenin's Theorem: any linear circuit = voltage source (Vth) + series resistance (Rth). Norton's Theorem: equivalent = current source (In) + parallel resistance (Rn). They are duals; conversion: Vth = In × Rn. Essential for circuit analysis, load matching, and troubleshooting. Applicable to AC circuits using impedance.
