Compare the calculated and measured values (for different values of R) and determine whether they agree or are very close in value. (Consider the measured value as very close if its difference with the calculated value is about of the latter). Explain your findings. Using the
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.
Compare the calculated and measured values (for different values of R) and determine whether they agree or are very close in value. (Consider the measured value as very close if its difference with the calculated value is about of the latter). Explain your findings.
Using the measured values, determine whether the algebraic sum of the currents entering and leaving node A (Fig. 2.1) satisfies or approximate Kirchhoff’s Current Law for different values of R. Show the algebraic sum on the space provided below for each value of R. (The set of measured values satisfies KCL if the algebraic sum is less than 0.1 mA = 0.0001 A)
