Short tutorial on how to calculate the fuse rating with simple example and formula.
A fuse rating is the current that is needed to blow or break the fuse in an electrical circuit. When a fuse has blown it removes electrical power from an electrical circuit. The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. Follow the below tutorial on how to calculate fuse rating of an electrical appliances using the simple formula.
Fuse Rating Formula:
Fuse Rating = Wattage / Voltage
Let us learn here how to calculate fuse rating of any electrical appliance with a neat example.
Example on Fuse Rating Calculation of Electrical Appliances:
Consider an electrical appliance whose wattage is 1000 and voltage is 230. Calculate Fuse Rating.
Given:
Wattage = 1000
Voltage = 230
Step 2:
Fuse Rating = Wattage / Voltage
Fuse Rating = 1000 / 230
Fuse Rating = 4.35
