If you connect 3 resistors, having values of 2 ohms, 3 ohms, and 5 ohms in parallel, will the total resistance be 2 ohms, greater than 5 ohms, or lie between 2 ohms and 5 ohms? Explain.

Answer (3)

If u want only WHether the total resistance is less than 2 or less than 5 or more than 5 ohms: there is a Simple way.
When you connect resistances in parallel, resultant resistance is always smaller than all of them. So it is less than 2 ohms .

3 1 ​ + 2 1 ​ + 5 1 ​ = 30 10 ​ + 30 15 ​ + 30 6 ​ = 30 31 ​ R t ​ = 31 30 ​ Ω ≈ 0.97 Ω

The total resistance when connecting 2 ohms, 3 ohms, and 5 ohms in parallel is approximately 0.968 ohms. This value is less than the smallest individual resistance of 2 ohms. Therefore, the total resistance will not be greater than 5 ohms, and it lies below 2 ohms.
