The correct Answer is:
To solve the problem of finding the equivalent resistance \( R \) of two resistors \( R_1 \) and \( R_2 \) connected in parallel, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Parallel Resistance Formula**: When two resistors are connected in parallel, the formula for the equivalent resistance \( R \) is given by: \[ \frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2} \] 2. **Rearranging the Formula**: To find \( R \), we can rearrange the formula: \[ R = \frac{R_1 \cdot R_2}{R_1 + R_2} \] 3. **Comparing with Individual Resistances**: Since \( R_1 > R_2 \), we know that both resistors are positive values. Therefore, the equivalent resistance \( R \) must be less than both \( R_1 \) and \( R_2 \). This is a property of resistors in parallel. 4. **Conclusion**: Thus, we can conclude that: \[ R < R_1 \quad \text{and} \quad R < R_2 \] Therefore, the correct statement is that the equivalent resistance \( R \) is less than either of the individual resistances \( R_1 \) or \( R_2 \). ### Final Answer: The equivalent resistance \( R \) is less than both \( R_1 \) and \( R_2 \). ---
