yes
when turned on the current is 2000/220V=9.09
since 9.09<10 its able to withstand

Answer: Yes the fuse will be able ti withstand ,when the air conditioner is switched on.

Explanation:

Power of air conditioner = 2 kW = 2000 W (1000 W=1kW)

Potential difference applied = V = 220 V

Fuse rating of the air conditioner = 10 A

Current used by the air conditioner = ?

[tex]power=current\times voltage= I\times V[/tex]

[tex]I=\frac{2000 W}{220 V}=9.1 A[/tex]

10 A >  9.1 A ,Yes the fuse will be able ti withstand ,when the air conditioner is switched on.
