Chapter 23, Problem 46A

To determine

Current supplied by voltage source.

Answer to Problem 46A

Current flowing through voltage source $I=4.45\text{ A}$ .

Explanation of Solution

Given:

Branch currents are

  $I_1=3.45\text{ A, }{I}_2=1\text{ A}$

Formula used:

For parallel circuit current through source is the sum of current flowing through each branch.

  $I=I_1+I_2+I_3+I_4+\mathrm{.............}{I}_n$

Where, $I$ is current flowing through source and $I_1,I_2,I_3,I_4\mathrm{.............}{I}_n$ are branch current.

Calculation:

Now, substituting the value of $I_1,I_2$ and solve.

  $\begin{array}{c}I=3.45+1\\ =4.45\text{ A}\end{array}$

Conclusion:

Therefore, current flowing through voltage source is 4.45 A.
