We started the class by doing "Nodal Analysis Lab"
Setup:
Measuring the resistance of the resistors
Making sure the power supply is 3V
Voltage across each resistors:
The rather messy one ( the setup that is used for regular ungrounded 3v power supply)
We change it around after knowing the black box is grounded;
Final setup (SO MUCH CLEANER THAN BEFORE!)
****Note****
-Turns out in the analog discovery box, it is internally grounded. This makes it unnecessary to put more grounding cable as if we would if we use regular power supply.
- Red cable is always +5V , while white cable is always -5 V. Yellow cable is adjustable through the wavegen tab.
Class notes:
Mesh analysis
Mesh analysis differs from nodal analysis in that one analyzes voltage, whereas the other one analyzes current.
Mesh is a loop that doesn't have any other loops within it.
When there is a current source that is in the middle of two meshes, we could combine them into a SUPERMESH!
Mesh analysis is only usable in planar circuit.
Summary:
- Analog discovery box enable us to reduce the number of cable needed vs. when we uses conventional power supply.
- I learn that we could have more than just 2 power supply out of the analog discovery box (3 that we uses today).
Mesh analysis is useful, but not usable in anything other than planar circuit.
