You're on a roll — here are the answers to the questions: 6.4 Draw clear transformer symbol diagrams to represent an air-core and a soft-iron core transformer. Air-core transformer: (0,0) to[coil, l=P] (0,2); (1,0) to[coil, l=S] (1,2); Soft-iron core transformer: (0,0) to[coil, l=P] (0,2); (1,0) to[coil, l=S] (1,2); [thick] (0.4,0) -- (0.4,2); [thick] (0.6,0) -- (0.6,2); 6.5 Explain what copper loss is and give two ways on how to reduce it. Copper loss (or I^2R loss) is the power dissipated as heat in the windings of a transformer due to the electrical resistance of the copper conductors when current flows through them. Two ways to reduce copper loss are: • Using thicker copper wires for the windings, which reduces their resistance. • Reducing the length of the windings by optimizing the transformer design. 6.6 Give TWO examples of transformers currently being used. • Step-up transformer: Used to increase voltage for long-distance power transmission. • Step-down transformer: Used to decrease voltage for distribution to homes and businesses. 6.7 Calculate the load current and load voltage in the transformer circuit below. The transformer circuit diagram required for this calculation is not provided in the image. Therefore, the load current and load voltage cannot be calculated. What's next?
