a resistance R is connected in across two batteries a and b connected in parallel. the open circuits emfs and internal resistances of the batteries are 12V, 2 ohms and 8V. 1 ohm, respectively. determine the ohmic value of R if the power absorbed by R is 7.656 watts
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.
