Question

What is the magnitude of the current \( i \) in the given circuit? 
 

Hint:

Kirchhoff's Current Law states that at any junction, the sum of currents entering equals the sum of currents leaving.

Answer 1

Using Kirchhoff’s Current Law (KCL), the sum of currents entering a junction equals the sum of currents leaving it:

\[ i = (6 \, \text{A} + 3 \, \text{A}) - (10 \, \text{A} + 3 \, \text{A}) = 4 \, \text{A}. \]
