The most appropriate value of fuse for a kettle rated 220v, 106kW is
ScanSolve AI Answer
Step-by-step solution
2 stepsThe power rating of 106 kW for a kettle is extremely high and unrealistic for a household appliance. It is highly probable that there is a typo in the question, and the intended power rating was 1.06 kW (1060 W). I will proceed with this assumption to provide a realistic fuse value for a kettle.
Calculate the operating current (I).
The formula for power is P = V × I, where P is power, V is voltage, and I is current.
Given:
Power (P) = 1.06 kW = 1060 W (assuming a typo in the question)
Voltage (V) = 220 VI = P / V
I = 1060 W / 220 V
I = 4.818 ADetermine the most appropriate fuse value.
A fuse should be rated slightly higher than the normal operating current to prevent it from blowing unnecessarily, but low enough to protect the appliance from overcurrent. Common standard fuse ratings include 1A, 2A, 3A, 5A, 10A, and 13A.
Since the calculated operating current is 4.818 A, the next standard fuse rating above this value is 5 A.The most appropriate value of fuse for a kettle rated 220 V, 1.06 kW (1060 W) is a 5 A fuse.
