Norton Theorem
Step 4
Calculate the current flowing through the 4Ω resistor.
By using Current Divider Rule (CDR),
iL= R N x IN = 3.927 x (2.115A) = 1.048 A
R +R L ( 3.927 +4)
N
The current flowing through the 4 Ω resistor = 1.048 Amps
Example 2
Solve for the current that goes through the 20 Ω resistor.
Figure 3.2(a)
Step 1
Remove the 20Ω resistor and replace the current source with an open circuit.
