Procedure:
1. Using only fixed value resistors available in your analog parts, design circuits which have the equivalent resistances listed below. For this, you may need to connect resistors in series and/or in parallel. These are the desired resistor values:
- 600 ohms (Hint: two resistors in parallel in kOhms)
- 800 ohms (Hint: you can add two 100 ohm resistors in series to the 600 ohms obtained above)
- 1.2k ohms (Hint: three resistors in series or two in parallel added to a resistor in series)
- 4k ohms (Hint: three resistors in series)
- 4.9k ohms (Hint: two resistors in parallel, both having the same value in kohm range, and then add this in series to the resistance that is in kOhm range)
- 9.1k ohms (Hint: use 3 resistors in series)
Per your convenience, the list of resistors included in your component kit is shown below:
- 10 ohms
- 1M ohms
Example: Assume we need to obtain a 3.5k ohm resistor using the above resistors. We can place two 6.8k ohm resistors in parallel and then connect it in series with a 100 ohm resistor, giving a 3.5k ohm resistor. Note that it may take up to four resistors to obtain the desired values being asked.
2. Once you obtain the circuit for each resistor, put them on the breadboard. Then, measure the equivalent resistance of each circuit using a Multimeter (use in Ohm-meter position). Compare it to the desired values. Determine how much tolerance you have for the desired resistor value. For example, if you measure 540 ohms for the first one, then you have a tolerance of 10%. Note: In order to place the correct resistors on the breadboard, you will need to know the color codes, as it will be difficult to use an Ohmmeter to find each resistance.
