The currents ia and ib in the circuit in Fig. P2.26 are 4 A and - 2 A, respectively. a) Find ig. b) Find the power dissipated in each resistor. c) Findvg. d) Show that the power delivered by the current source is equal to the power absorbed by all the other elements
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.
