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.
For the following circuit, write the KVL equations for the three distinct closed path loops (left loop, right loop, and outer loop) and KCL at the top node. In your equations, use the voltage and current designations provided. These answers are all in variables.
