Question

# Four unequal resistors are connected in parallel with each other. Which one of the following statements is correct about this combination?

## The equivalent resistance is less than that of the smallest resistor.The equivalent resistance is equal to the average of the four resistances.The equivalent resistance is midway between the largest and smallest resistance.The equivalent resistance is more than the largest resistance. Hint:

## The correct answer is: The equivalent resistance is less than that of the smallest resistor.

### When four unequal resistors are connected in parallel with each other, the equivalent resistance is less than that of the smallest resistor.  The resistance in parallel combinations is comparatively lesser than that of series combinations. When unequal resistors are connected in parallel, the total resistance becomes less, and the current flow increases. So the equivalent resistance becomes less than that of the smallest resistor (when the resistors with different resistances are connected in parallel.)  #### With Turito Foundation. #### Get an Expert Advice From Turito.
