A battery with a terminal voltage of Vab = 9 V is connected to a circuit having three 10-ohm and one 5-ohm resistors all in series. Assuming that the battery has negligible internal resistance, determine the total power dissipated by the resistors and the power supplied by the battery.
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.
