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.
The voltages are not the same n here the voltage source in this problem is 50 volt while the voltage in the first similar problem is 80 volt. This clearly indicate that there is a noticeable different between the answers of this problem, and the first problem I posted early. Would you review it and repost it if possible. I just want to understand
