Introduction: In this experiment we focused on a superposition, this principle states that whenever such a circuit is driven by more than one independent source, the total response (voltage or current) may be found by algebraically combining the responses of each individual independent source acting alone. We first started off by measuring the circuit elements that we were going to be using for this lab. Our first element was the 1K Ω resistor and it measured 1.03K Ω, the next 3.3K Ω resistor measured 3.37K Ω, and our final element the 10K Ω resistor measured out to 9.908K Ω. The circuit used for the lab was the same for both parts, the only difference being the deactivation of each power supply. The first circuit we created had a 10 V power supply, which was then connected in series to the 1.03K Ω resistor, connected in parallel with that was the ammeter and the 9.908K Ω resistor, and then to the right side of the circuit there was the 3.37K Ω resistor and 20 V power supply connected in series. For the first part of the lab we started by deactivating 10 V source by removing the power supply, and thus shorting the circuit. After we finished this, we used the digital multimeter to measure the voltage and current across the 9.908K Ω resistor. For the second part of the lab, once we had the measurements for the deactivation of the 10V power supply, we reconnected this power source. We then deactivated the 20 V source by removing the power supply and thus creating a short circuit. After we used the digital multimeter to measure the voltage and current across the 9.908K Ω resistor. After this, we reconnected the 20 V power source (so that both the 10.0035 V and 19.999 V were conne
