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.
Switch rating
It is defined as the maximum allowable voltage or current that can be passed through the switch without damaging the switch.
If we pass or apply current or voltage more than the given rating then the switch will get damaged. Generally, the rating of the switch is given by the manufacturer end.
