Explanation:
The United States uses a voltage of 110-120 volts, while Singapore uses a voltage of 220-240 volts. This means that if you plug an electronic device from the US into an outlet in Singapore, it will likely be damaged. However, you can use a voltage converter to convert the voltage from 220-240 volts to 110-120 volts, which will allow you to safely use your electronic devices from the US in Singapore.
