Description:
I suggest here that you experimentally discover kirchhoff's current law for series and parallel circuit. Instructions are displayed here.
two light bulbs connected in series (5 pts)
1. Realize this circuit :
2. (1 pt) Copy out its diagram, adding the ammeter which will measure I1.
3. (1 pt) Measure and note I1, I2 & I3.
4. (1 pt) Compare I1, I2 & I3.
5. (2 pts) Write a concluding sentence.
two light bulbs connected in parallel (5 pts)
6. Realize this circuit :
7. (1 pt) Copy out its diagram, adding the ammeter which will measure I1.
8. (1 pt) Measure and note I, I1 & I2.
9. (1 pt) Compare the results.
10. (2 pts) Write a concluding sentence.
Definition
Kirchhoff's Current Law: There are several ways to state the KCL:
- the same current flows through components connected in series.
- sum of the currents entering a node is equal to the sum of those leaving.
