Correct Answer: Option A
Explanation:
For parallel resistance,
\(\frac{300 \times 200}{500}\)
\(= 120 \Omega \)
Therefore it is when a 300Ω resistor is connected to it in parallel
For parallel resistance,
\(\frac{300 \times 200}{500}\)
\(= 120 \Omega \)
Therefore it is when a 300Ω resistor is connected to it in parallel
