The equivalent resistance of the series combination is : 3XΩ
Equivalent Resistance is the total resistance in circuit (i.e parallel or series circuits).
Bulb in series have the same resistance. Therefore each Bulb has a resistance of XΩ
equivalent resistance = [tex]R_{1}[/tex] + [tex]R_{2}[/tex] + [tex]R_{3}[/tex]
Let [tex]R_{1}[/tex] represent resistance of bulb one
[tex]R_{2}[/tex] represent resistance of bulb two
[tex]R_{3}[/tex] represent resistance of bulb three
equivalent resistance = X + X + X
equivalent resistance = 3XΩ
In conclusion, the equivalent resistance of the series combination of Three identical lamps connected in series with each other with a resistance of X ohms each is 3XΩ
