Answer :
Final answer:
Buck boost transformers are used for voltage correction only with ( option c is the correct answer)constant loads, adjusting voltage levels without interrupting the utility's power flow. Step-up transformers are used to increase voltage and decrease current, and vice versa for step-down transformers. Reducing resistance is the choice to increase power dissipation in a circuit.
Explanation:
Buck boost transformers should only be used for voltage drop correction when the load is constant( option c is the correct answer). This type of transformer is effective for stabilizing the voltage level when the electrical load remains unchanged. It is designed to either step-up (increase) or step-down (decrease) voltages to correct the voltage drops across the lines. A step-up transformer increases voltage and decreases current, while a step-down transformer decreases voltage and increases current, to ensure that power transmission is efficient over long distances.
When choosing to increase the power dissipated in a circuit with constant current, one should reduce the resistance to increase the power. Selecting the right transformer type is essential for managing power systems, and it should match the characteristics of the electrical load.
