Three unequal resistances are connected in parallel. Two of these resistances are in the ratio 1:2. The equivalent resistance of these three resistors connected in parallel is \(1 \Omega\). What is the highest resistance value among these three resistances if no resistance is fractional?
- A \(10 \Omega\)
- B \(8 \Omega\)
- C \(15 \Omega\)
- D \(6 \Omega\)
Answer & Solution
Correct Answer
(D) \(6 \Omega\)
Step-by-step Solution
Detailed explanation
Let the resistances be \(R_1, R_2\) and \(R_3\), respectively. According to the question, equivalent resistance in parallel \(=1 \Omega\) In parallel combination, the equivalent resistance is given by Here,…
