Consider the circuit shown below. Label current in branch ab as I1, current in branch cd as I2, and current in branch ef as I3. Write three equations with I1, I2, I3 by applying Kirchhoff’s first law(current law) to point d and Kirchhoff’s second law(voltage law) to abcda and cdefc loops
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.
