Question

Derek was giving electricity exam and one of the questions was “Three resistors of resistance 4Ω, 
8Ω and 12Ω are connected in parallel. Find the equivalent resistance.” He calculated using the 
formula and got the answer as 6Ω. He immediately knew that he did some mistake in the 
calculation. How could he possibly know that?


Solution

But in case of parallel connection of resistors the equivalent resistance is smaller than the individual resisters.

since we add the inverse of each resistor value and equate with the inverse of their equivalent resistance.
