Most Upvoted Answer
A uniform wire of resistance 36 ohm is bent in the form of a circle . ...
**Solution:**
When a uniform wire of resistance 36 ohm is bent in the form of a circle, the resistance across any two points in the circle is given by:
$R = \frac{2R_0}{\pi}$
where R is the effective resistance across any two points in the circle, and R0 is the resistance of the wire.
**Step 1: Find the resistance of the wire**
The resistance of the wire is given as 36 ohm.
**Step 2: Find the radius of the circle**
Let the radius of the circle be r.
**Step 3: Find the length of the wire**
The length of the wire is given by the circumference of the circle, which is 2πr.
**Step 4: Find the resistance across A and B**
The effective resistance across A and B is given by:
$R = \frac{2R_0}{\pi} = \frac{2 \times 36}{\pi} = 22.91$ ohm (approx.)
Therefore, the effective resistance across A and B is approximately 22.91 ohm.
