of the easiest ways to avoid overloading a power strip is to understand the relationship between watts, volts, and amperes.
The basic electrical formula is:
Power (Watts) = Voltage (Volts) × Current (Amperes)
This means that electrical current can be estimated by dividing power by voltage:
Current (Amperes) = Power (Watts) ÷ Voltage (Volts)
For example, consider a power strip rated at 10 amperes and used on a 230-volt electrical supply.
Its theoretical maximum power capacity is:
10 × 230 = 2,300 watts.
Now imagine connecting the following appliances:
Electric kettle: 2,000 watts
Coffee
