      Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?              [NCERT]

    Answer:

                      Coils of electric toasters and electric irons are made of an alloy rather than a pure metal because (i) the resistivity of an alloy is much higher than that of pure metal and (ii) an alloy does not undergo oxidation easily even at high temperature.
