Question

Three resistors 2 Ω, 3 Ω, 5 Ω in series. Equivalent resistance?

1. **Circuit Configuration**: When resistors are connected end-to-end, they are said to be in **series**.
2. **Formula**: The total effective resistance ($R_{eq}$) is the algebraic sum of individual resistances:
   $R_{eq} = R_1 + R_2 + R_3 + \dots$
3. **Calculation**:
   - $R_1 = 2 \text{ } \Omega$
   - $R_2 = 3 \text{ } \Omega$
   - $R_3 = 5 \text{ } \Omega$
   - $R_{eq} = 2 + 3 + 5 = 10 \text{ } \Omega$
4. **Result**: The equivalent resistance is **10 $\Omega$**.
