Q:

Two metallic wires made from copper have same length but the radius of wire 1 is half of that of wire 2. The resistance of wire 1 is R. If both the wires are joined together in series, the total resistance becomes

 

A) 2R B) R/2
C) 5R/4 D) 3R/4
 
Answer & Explanation Answer: C) 5R/4

Explanation:

So, resistance of Wire 2 is R/4 as radius is half of wire 1, so area would be 4 times of wire 1.

Now for resistance in series. R= R1 + R2.

Therefore, Final R= R + R/4 = 5R/4
