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.
A) Use any analysis method to calculate the voltage Vo and the power dissipated by the dependent source indicating whether the dependent source absorbs or generates power.
Indicate the method you used in the analysis and explain your procedure.
B)If the 2 Ω resistor, where the voltage Vx is defined, is short-circuited, what circuit would be left? What would be the value of the volage Vx? What would happen to the current dependent source? Explain your reasoning.
