1. 50 V Consider the following circuit: 10 Q2 www I₁ www 15 Q2 A 3 Ω www 13 U9 9 V 9Ω + 9 V A. Redraw the circuit in your blue book and label the three loops in the circuit. B. Write Kirchhoff's voltage law equations for each of the loops you labeled in part C. Write a Kirchhoff's current law equation for node A. D. Using your equations from parts b and c, solve for the three unknown branch currents shown in the diagram. 3 V 12 Q2
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.
