For the circuit shown in the figure, find the current passing through 10 Ω resistor.
|Key concepts : Kirchhoff's Current Law (Junction law)
This law is based on law of conservation charge. It states that "The algebraic sum of the currents meeting at a point of the circuit is zero' or total currents entering a junction equals to the total current leaving the junction.
It is also known as KCL (Kirchoff's current law).
