B) You are required to analyze the operation of DC circuit shown in Fig.2 and apply Ohm's law and Kirchhoff's voltage and current laws to find all the Voltages (with the associated polarities) and currents (with the associated direction)for all resistors. (Show all steps, equations, and calculations). IR6 R1 2.2kQ R2 6.8kQ R3 6.8kQ V1 9V R6 2.2kQ R5 26.8kQ V2 .9V V3 9V Figure 2: DC-Circuit C R4 32.2kΩ
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.
You are required to analyze the operation of DC circuit shown in Fig.2 and apply Ohm’s law and
Kirchhoff’s voltage and current laws to find all the Voltages (with the associated polarities) and
currents (with the associated direction)for all resistors. (Show all steps, equations, and calculations). C)Your manager asked you to present an analysis for the scientific data related to DC circuit.
Firstly, he asked you to replace V1 with open circuit and V3 with short circuit and do the
following:
a. Calculate the equivalent resistance, all currents and voltages.
b. Connect the circuit in the Laboratory and fill the results in Table 2 (Show all
calculations).
