An engineer in an electronics laboratory has a large batch of identical 24 Ω resistors. She is tasked with designing a component subnet that uses exactly three of these resistors in a single combination.
Which of the following equivalent resistance values cannot be constructed using exactly three of these 24 Ω resistors?
8 Ω8\ \Omega8 Ω
12 Ω12\ \Omega12 Ω
16 Ω16\ \Omega16 Ω
36 Ω36\ \Omega36 Ω
