A. A 300Ω resistor is connected to it in parallel
B. An 80Ω resistor is connected to it in series
C. A 150Ω resistor is connected to it in parallel
D. A 240Ω resistor is connected to it in series

Correct Answer:

Option A – A 300Ω resistor is connected to it in parallel

Explanation

For parallel resistance,

300×200/500

=120Ω

Therefore it is when a 300Ω resistor is connected to it in parallel
