Question

A man uses an electric iron 250 watts and an electric stove cooker 1.25kw of its power supply. what is the appropriate fuse that should be used in the electric current when the two items are switched on at the same time (main voltage =240v)​

Answer 1

First, we need to convert the power consumption of the electric stove cooker from kilowatts to watts:

1.25 kW = 1,250 watts

Then, we add the power consumption of both appliances:

250 watts + 1,250 watts = 1,500 watts

To calculate the appropriate fuse, we divide the total power consumption by the voltage:

1,500 watts / 240 volts = 6.25 amps

Therefore, an 6.25-amp fuse would be appropriate for these appliances.
