A. Analog to Digital
B. Convert High AC to Low AC voltages
C. Convert Low AC to High AC voltages
D. Both B & C
🧠 Explanation:
A transformer’s functions include stepping up or stepping down voltage and isolating circuits, making “Both B & C” correct. Transformers adjust voltage for efficient power transmission or device compatibility and provide safety by isolating electrical circuits. They are vital in power distribution, electronics, and industrial systems, ensuring energy efficiency and equipment protection. Understanding their dual roles is crucial for electrical engineering, as transformers enable safe and efficient power delivery across grids and devices, from household appliances to large-scale power networks, supporting modern infrastructure and technological functionality worldwide.
