In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance. What is the total resistance?
Sauron [17]

Answer:

17 ohms

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).
