Description:
I suggest here that you experimentally discover kirchhoff's current law for series and parallel circuit. Instructions are displayed here.
Series :
1. Connect bulb and resistor in series (don't use the long conductor). Draw the diagram of this construction.
2. Measure and note I1, I2 and I4.
3. Compare the results.
4. Write a concluding sentence.
Parallel :
5. Connect bulb and resistor in parallel. Draw the diagram of this assembly (use the long conductor to complete the circuit).
6. Measure and note I1, I2, I3 and I4.
7. Compare I1 and (I2 + I3).
8. Compare (I2 + I3) and I4.
9. Compar I1 (... output of generator) and I4 (... input).
10. Write concluding sentences.
Good Work !
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.
