BASIC CIRCUIT ANALYSIS

Case Based Study- Each case study question will be assigned to a group of 9 students based on the nominal roll order, and the last batch will be assigned 8 students. 1. A rural electrification project faces voltage drop issues at the consumer end due to long distribution lines. Analyze the impact of conductor resistance on voltage regulation using Ohm’s Law. Suggest suitable engineering solutions to minimize power loss and improve efficiency. (Industry: TANGEDCO | Bloom’s Level: L4 – Analyze | CO1) 2. A manufacturing unit reports frequent fuse failures in a multi-branch DC circuit. Examine the circuit using Kirchhoff’s Current and Voltage Laws to identify possible fault locations. Justify how proper current distribution analysis prevents system failure. (Industry: L&T Electrical | Bloom’s Level: L5 – Evaluate | CO1) 3. A residential building experiences unequal brightness in lighting circuits when appliances are switched on. Analyze the difference between series and parallel connections and justify why domestic wiring is always designed in parallel configuration. (Industry: Schneider Electric | Bloom’s Level: L4 – Analyze | CO1) 4. A battery-operated medical device shows reduced output voltage under load conditions. Evaluate the effect of internal resistance in practical voltage sources and justify the importance of source modeling in sensitive electronic equipment. (Industry: Philips Healthcare | Bloom’s Level: L5 – Evaluate | CO1) 5. A power supply unit in an electronics lab produces excessive heating at high frequencies. Analyze the behavior of inductive and capacitive components in AC circuits and examine how reactance affects circuit performance at varying frequencies. (GATE EE | Bloom’s Level: L4 – Analyze | CO1) 6. A domestic inverter system shows difference between displayed voltage and effective heating performance of appliances. Evaluate the significance of RMS value in AC circuits and justify why electrical equipment ratings are based on RMS rather than peak value.
