KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
After the circuit in Figure 2 has been in operation for a long time, a person who will not be named accidentally dropped a metal fork on it, creating a connection between the nodes to and b. Assuming the resistance of the fork is negligible, find the current through the fork then of the accident
