6.6.1. Iterative Method

Try these first

1. 1.

   What is an iterative method?

   Hint

   Think of how you could keep guessing a number until you find the correct one.

2. 2.

   What voltage drop is commonly assumed for silicon diodes?

   Hint

   Consider standard values you learn for electronic components.

3. 3.

   What is the primary use of the iterative method in circuit analysis?

   • To find the resistance
   • To refine guesses
   • To calculate capacitance

   Hint

   Think about what iterative means in mathematics.

4. 4.

   True or False: A diode can be modeled as having high resistance when it is in the off state.

   • True
   • False

   Hint

   Consider how diodes operate in both on and off states.

5. 5.

   Given a non-linear circuit with a silicon diode and components that include a 10kΩ resistor and a voltage supply of 5V, calculate the current and voltage under both iterative and piecewise linear models. Show all workings.

   Hint

   Start from your initial guess and iterate while comparing results.

6. 6.

   Design a simple series circuit using a diode and resistor, and analyze its behavior under different input voltages using both large signal and small signal equivalent circuits.

   Hint

   Draw diagrams that illustrate circuit operations and use known values for calculations.
