Explanation:
a) P = IV
2000 W = I (230 V)
I = 8.7 A
b) The fuse must be rated for a higher current than the kettle, so use the 13A fuse.
c) Double insulation means there are two layers of insulation, insuring that the wires cannot touch the outer casing of the kettle and protecting the user from electrical shock.
d) V = IR
230 V = (8.7 A) R
R = 26.5 Ω
