You have given the above diagram of a resistor network. The numerical values of the resistors are R1=12kΩ, R2=2kΩ, R3=8kΩ, R4=2kΩ, R5=12kΩ, R6=2kΩ, R7=12kΩ. And the e.m.f s are V1=13.0volts, V2=15.0volts, V3=15.0volts, a) Find the equivalent resistance across the terminal TS. b) Draw the diagram and then apply KVL and KCL to it. Write down the equations accordingly. c) Find the value of the current passing through resistor R2.
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.
