Q.39.A wire of resistance R bent in form of closed circle, what is the resistance across diameter of thecircle. |
|
Answer» Given, resistance of wire is R when, it is bend in a form of circle then the resistance across its diameter is --- 1/R' = 1/R/2 + 1/R/2 => 1/R' = 2/R + 2/R => 1/R' = 4/R => R' = R/4 hence, the resistance across the diameter of circle is R/4. |
