How is a fuse similar to a switch in terms of function?

The purpose of a switch or a fuse is to break or connect an electric circuit, but they must be correctly connected in the home. A switch or a fuse in an electrical circuit is always connected to the live wire so that the socket or appliance is not live when switched off.

Explanation:

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
