Concept explainers

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.

I need a detailed answer on this please. 1.Depending on voltmeter/ammeter terminal connection to the components, you might find differentsigned voltage and currents values for the same component. This causes different signed powervalues for the same components therefore we cannot state whether components generate orabsorb power. What is your solution to this chaos?
