Question

Nichrome and copper wires of same length same radius are connected in series. Current is passed .wich wire heat up moreand why

Answer 1

Nichrome wire heats up quickly because the resistance of the wire of nichrome is greater than copper.
Hope it will helps

Answer 2

Hey !!

Question

Nichrome and copper wires of same length same radius are connected in series. Current I is passed through them. Which wire heated up more and why ?

Answer

I is same in both

           when I is constant

      The heat produced is constant

              H = I²Rt

        H ∝ R

R ∝ f       f is higher for nichrome.

So, R is higher for nichrome.

More heat is produced in Nichrome wire.

DETAILED ANSWER FOR BETTER UNDERSTANDING

Among the two wires having similar length and radius, Nichrome wire gets heated up more as compared wire since resistivity of Nichrome is more than that of Copper. Also, Nichrome wire is a good conductor of current and have very less resistance, so it will heat sooner as compared to Copper.

GOOD LUCK !!
