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.
1. a) Find an expression for the equivalent resistance of two resistors
of value R in parallel.
2. b) Find an expression for the equivalent resistance of n resistors of
value R in parallel.
3. c) Using the results of (a), design a resistive network with an
equivalent resistance of 5 kΩ using two resistors with the same
value from Appendix H.
4. d) Using the results of (b), design a resistive network with an
equivalent resistance of 4 kΩ using a minimum number of identical
resistors from Appendix H.
