Q3. An electrical signal can be represented in either Thevenin form or Norton From. However, Norton representation is preferred when
Ans. 
Norton representation is preferred when the load impedance is known and fixed.
• Norton representation is preferred when the load impedance is known and fixed, as it simplifies calculations.

• Thevenin representation is preferred when the load impedance is unknown or variable.

• Norton equivalent circuits are easier to analyze in terms of current flow and power calculations.

• Thevenin equivalent circuits are easier to analyze in
