In the circuit shown, use KCL, KVL, and Ohm’s law to choose the value of Vs so that the current through R2 is 10 mA and the current through R3 is 25 mA, with the voltages and currents defined at the right. How much power will be generated by the source?
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.
