Calculate the correct fuse that should be used for a 230V,1KW electric hair dryer.​
zzz [600]

Answer: 4 A

Explanation:

Given

Voltage V=230\ V

Power P=1\ kW

Power is given by P=VI\\

Insert the values

\Rightarrow 1000=230\times I\\\\\Rightarrow I=\dfrac{1000}{230}\\\\\Rightarrow I=3.84\ A

The rating of fuse is slightly higher than the normal operating conditions. Therefore, a 4 A fuse should be used here.

An object possessing an excess of 6.0x10^6 electrons has a net charge of
guajiro [1.7K]
A single electron has a charge of
e=-1.6 \cdot 10^{19}C
Therefore, if we have an excess of N=6.0\cdot10^6 electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
Q=Ne=(6.0\cdot10^6)(-1.6 \cdot 10^{-19}C)=9.6 \cdot 10^{-13}C
