CALCULATE THE RESISTANCE OF A 2M LONG NICHROME WIRE OF RADIUS 0.321MM.RESITIVITY OF NICHROME IS 15INTO10^-6 OHM METER.IF A POTENTIAL DIFFERNCE OF 10 V IS APPLIED ACROSS THE WIRE ,WHAT WILL BE THE CURRENT IN THE WIRE.

Dear Student, 
Please find below the solution to the asked query: 
Resistance:R=ρLπr2=15×10-6 × 2π × 0.321x10-32=92.7 ohmsCurrent:I=VR=1092.7=0.11 A
Hope this information will clear your doubts about    Resistance.                   
If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.
