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.
The currents i1 and i2 in the circuit are 20 A and 15 A, respectively.
1. Find the power supplied by each voltage source.
2. Show that the total power supplied equals the total power
dissipated in the resistors.
