Answer :
Final answer:
To buck 10% using a transformer, connect the lower voltage tap on the primary side and the higher voltage tap on the secondary side.
Explanation:
To connect a transformer to buck 10%, you would need to connect the primary voltage (input) to the lower voltage tap on the primary side and the secondary voltage (output) to the higher voltage tap on the secondary side.
For example, if the primary voltage is 100V and you want to buck it by 10%, you would connect it to the 90V tap on the primary side. Similarly, if the secondary voltage is 200V and you want to buck it by 10%, you would connect it to the 220V tap on the secondary side.
This connection allows the transformer to reduce the voltage by 10% from its nominal value.
