Answer 1

HEY BUDDY...!!!

HERE'S THE ANSWER...

_______________________

⏺️ We know resistance

=> R = p l / A

⏺️ Where p is resistivity of material , l length of material , A is area of crossection or thickness

⏺️ We also know resistance of Manganin is very high that resistance of copper

⏺️From above statements we can conclude

=> Rc ( resistance of copper )

=> Rc = pc l / A1_______( 1 )

=> pc ( resistivity of copper )

⏺️Now

=> Rm = pm l / A2 ________( 2 )

Now dividing both eqn

=> Rm = Rc ( given )

=> pm / A2 = pc / A1

=> pm >> pc

So A1 > A2

⏺️ Hence copper is more thick



HOPE HELPED..

GOOD MORNING
