Basic Concepts 9
Solution: We can redraw the circuit as shown in
Figure 1.13 and find the equivalent resistance as
shown using successive steps.
Thus, the equivalent resistance is R.
Example 1.5 In the circuit shown in Figure 1.14,
calculate values of branch currents I
1
and I
2
.
Solution: In the circuit, total current I is divided into I
1
and I
2
. We will first calculate the total current I and then
calculate the branch currents using current divided rule.
