A uniform wire of resistance R is cut intotwo Equal halves and these half are joinedin parallel. What is the resistance of thewire. |
|
Answer» Answer: R/4 will be the RESISTANCE. Explanation: Given the resistance of the uniform wire is R. If we cut it into two equal half Then resistance of the ONE part of wire will be R/2 and that of another part will be R/2 Since these wires are connected in parallel So, 1/Req = 1/ (R/2) + 1/(R/2) ⇒2/R + 2/R ⇒4/R Now we have 1/Req = 4/R So Req = R/4 |
