Find the currents flowing in the circuit in Figure 21.52. Explicitly show how you follow the steps in the ProblemSolving Strategies for Series and Parallel Resistors.

Solution 38PE

Apply the formula of node at point a,

I3 =I1 + I2

I1 + I2 -I3 = 0…… (1)

Apply the loop rule in loop aklefghija as follows,

40.5 I2 + 78.25 I3 = 18…… (2)

Apply the loop rule in loop abcdelka as follows,

25.1 I1 + 50.1 I2 = 24…… (3)

Now, substitute the value of I3 from equation (1) into equation (2), we...
