Transformer types (Step-down, Center-tap, Autotransformers) and ratings. Half and full-wave rectification and filter circuits. Module 5: Amplifiers (15% Weighting)

come in. These devices convert physical parameters—such as temperature, pressure, or light—into electrical signals. Whether it is a thermistor monitoring motor heat or a photoelectric cell counting items on a conveyor belt, understanding how to interface these sensors with electronic circuits is a hallmark of the N4 level. Conclusion

Total current entering a junction equals the total current leaving it.

The exam weighting is not equal. together account for 40% of the total marks. Spend 40% of your study time exclusively on these two modules. Once you have mastered them, move on to Power Supplies and Amplifiers (another 30%), and then the remaining modules.
