Breif the difference in the active and passive element.
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.
Breif the difference in the active and passive element.
In case of the V-I plane; the passive elements provide only positive impedance whereas in the active element the impedance can be negative as well.
The power is absorbed by the passive element and in case of the active element the power is delivered.
