Answer 2

17 ohms

Step-by-step explanation:

Given that,

In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.

We need to find the total resistance of the circuit.

The equivalent resistance for series combination is given by :

`R_(eq)=R_1+R_2+....`

For 17 light bulbs, the equivalent resistance is given by :

`R_(eq)=R+R+....\text{upto 17 terms}\\\\R_(eq)=17R\\\\=17`

Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
