Question

To handle differing voltages in multiple countries, most power supplies have _______________ options.

a) Voltage conversion
b) Multi-country
c) Auto-switching
d) Universal compatibility

Answer 1

Most power supplies are equipped with auto-switching options to handle different voltages, thereby ensuring universal compatibility without damaging the equipment.

Step-by-step explanation:

To handle differing voltages in multiple countries, most power supplies have auto-switching options. Auto-switching power supplies are capable of detecting the input voltage of the electricity supply where the device is plugged in. This feature allows the power supply to adjust accordingly to the local voltage standard without the need for manual intervention, providing universal compatibility. For instance, while the United States operates on 110 volts, much of Europe uses 220 volts. With auto-switching capability, the same device can be used in both regions without the risk of underpowering or damaging the equipment due to voltage differences.
