(a) State Kirchhoff’s current law.
(b) Explain briefly how the conservation of electric charge at a junction leads to this law.
(c) A node N in a circuit is connected to three conductors. At a certain instant a current of 2A enters the node through conductor 1, while a current of 3A leaves the node through conductor 2. Qualitatively discuss the magnitude and direction of the current in conductor 3 so that charge does not accumulate at the node.
