The correct Answer is:
To solve the problem, we need to find the equivalent resistance when n similar conductors, each with resistance R, are connected in series. ### Step-by-Step Solution: 1. **Understanding Series Connection**: - In a series connection, the total or equivalent resistance (R_eq) is the sum of the individual resistances. 2. **Identifying the Individual Resistances**: - Given that there are n conductors and each has a resistance of R, we can denote the resistances as R1, R2, ..., Rn, where each Ri = R. 3. **Applying the Formula for Series Resistance**: - The formula for the equivalent resistance in series is: \[ R_{eq} = R_1 + R_2 + R_3 + ... + R_n \] - Since all resistances are equal (R), we can write: \[ R_{eq} = R + R + R + ... + R \quad (n \text{ times}) \] 4. **Calculating the Total Resistance**: - This can be simplified to: \[ R_{eq} = n \times R \] 5. **Final Result**: - Therefore, when n similar conductors each of resistance R are connected in series, the resultant resistance is: \[ R_{eq} = nR \] ### Conclusion: The equivalent resistance when n similar conductors of resistance R are connected in series is \( nR \).
