| Aim - To find the
resistances of unknown resistors |
Instructions |
| |
- Select resistor A to be the unknown resistor
|
- Click on a yellow connector, to select a resistor on the resistance board.
|
- Find the value of the resistance of the resistance board which balances the Wheatstone
Bridge and find the value of resistance A
|
- Repeat to find the value of resistance B and C
|
- Replace R2 with a 10 k W resistor
|
- Predict the value of the resistance board that will balance the Wheatstone Bridge for
each of the resistors A B and C with this value of
R2.
