AIM: To investigate the current divider rule.

 

 

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

 

Table 2

Vin(V)	I1(mA)	I2(mA)	I3(mA)

1.  Close switch S and set Vin to 2 V.
2.   Read and record in Table 2 the values I1, I2 and I3.
3.   Repeat step (e) for the other values of Vin in Table 2.
4.   Open switch S.
5.   Using the values in Table 2, plot graphs of:

(i)  I2 on the vertical axis against I1 on the horizontal axis;
(ii) I3 on the vertical axis against I1 on the horizontal axis.

•   Determine the slopes of the graphs in (h)(i) and (h)(ii).
•   Compare the ratio with the slope of the graph in (h)(ii).
