The meaning of a bulb rated as 10W~220V is as follows:

- 10W: This refers to the power consumption of the bulb. It indicates that the bulb consumes 10 Watts of electrical power when it is in operation. The Watt (W) is the unit of power and is used to measure how much energy the bulb consumes.

- 220V: This indicates the voltage at which the bulb operates. In this case, the bulb is designed to work with a standard voltage of 220 Volts. The voltage is the measure of the electric potential difference between two points in an electrical circuit and determines the amount of electrical pressure required for the bulb to work properly.

So, in summary, a bulb rated as 10W~220V consumes 10 Watts of power and operates at a voltage of 220 Volts.
