AIM: To demonstrate Kirchhoff’s Laws.

1.   Connect the circuit as shown in Figure 1.
2.   Ask the Supervisor to check the circuit connection.
3.   Copy Table 1 into your answer booklet.

Table 1

1.   Switch on the power supply unit.
2.   Measure and record in Table 1 the voltages V1, V2 and current I1.
3.   Switch off the power supply unit.
4.   Replace R2 (2.2 kΩ) resistor with the 4.7 kΩ resistor.
5.   Switch on the power supply unit.
6.   Measure and record in Table 1 the corresponding values of V1, V2 and                          

current I1.

1.   Switch off the power supply unit.
2.   Complete Table 1.
3.   Using the results in Table 1, verify Kirchhoff’s
