Question

4.
In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance. What is the total resistance?

34 ohms

1/17 ohms

17 ohms

5 ohms

Answer 1

In a series circuit, the total resistance is the sum of the individual resistances. Given that there are 17 light bulbs, each with a resistance of 1 ohm, you can calculate the total resistance as follows:

Total Resistance (R_total) = R1 + R2 + R3 + ... + R17 = 1 ohm + 1 ohm + ... + 1 ohm (17 times)

So,

R_total = 1 ohm × 17 = 17 ohms

Therefore, the total resistance in the circuit is **17 ohms**.
