Question

If several resistances are parallel, their equivalent resistance will be:

• A. More than each resistance
• B. Less than each resistance
• C. Equal to each resistance
• D. None of these

Hint:

Parallel connections reduce resistance, series increases it.

Answer 1

The Correct Option is B

Step 1: Formula.
For parallel: $\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + ...$
Step 2: Property.
$R_{eq}$ is always less than the smallest individual resistance.
Step 3: Conclusion.
Hence, equivalent resistance in parallel is less.
