Which of the following is most suitable for protecting the circuit of 2000W electric iron connected to a 250V mains?
P = IV \(\Rightarrow\) I = \(\frac{2000}{250}\)
= 8A
The fuse rating should be higher than the calculated current to avoid nuisance blowing, but still protect the circuit. Therefore, the most suitable fuse rating from the options provided would be: 13A
