Apply the scientific method to validate both Kirchhoff voltage law (KVL) and Kirchhoff current law (KCL) for the above circuit to find I1, I2, I3, I4, I5 and IS. Show your steps: Use circuit theorem to calculate the power consumed in R1 Calculate the voltage across 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.
You are given the below circuit, answer the following questions and show the steps of your solution in details.

- Apply the scientific method to validate both Kirchhoff voltage law (KVL) and Kirchhoff current law (KCL) for the above circuit to find I1, I2, I3, I4, I5 and IS. Show your steps:
- Use circuit theorem to calculate the power consumed in R1
- Calculate the voltage across R2
- Use the falstad simulator (https://www.falstad.com/circuit/) to:
- Draw the above circuit (Note: screenshots must be included in your report)
- Write down the obtained results from the simulator (Note: screenshots must be included in your report)
- Compare and evaluate the results of the simulator and the results that you had calculated in parts a, b and c.
- Using the simulator, fill out Table 1 below for the given V1
- Plot V1 and IS values obtained in part (e) using a software that you choose (i.e. Excel, MATLAB…etc.)
- In your own words, discuss scientifically the meaning of the results shown in your plot.
