Use information in fig .6.80 to calculate A. The source voltage E B.the resistance R2 c the current l1 D.the source current Is E The power supplied by the source F. The power supplied to the resistor R1 and R2 G. Compare the power calculated in part(e) to the sum of the power delivered to all the resistor.
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.
