Four resistors, each of resistance R, are connected as shown in the figure below.
Which of the following options is correct?
- A The total resistance between points 3 and 6 is 2 R.
- B The total resistance between points 2 and 4 is \(0.5 \mathrm{~R}\).
- C The total resistance between points 1 and 3 is 0.5 R.
- D The total resistance between points 1 and 6 is \(3.5 \mathrm{R}\).
Answer & Solution
Correct Answer
(B) The total resistance between points 2 and 4 is \(0.5 \mathrm{~R}\).
Step-by-step Solution
Detailed explanation
Points 2 and 3 are connected by a wire \(\Rightarrow\) same node (A). Points 4 and 5 are connected by a wire \(\Rightarrow\) same node (B). The middle resistor (2 to 5) and bottom resistor (3 to 4) are both connected between node A and node B \(\Rightarrow\) they are in…
