Would replacing the Nichrome with the copper wire of the same size result in a higher current
Question:
Would replacing the Nichrome with the copper wire of the same size result in a higher current or lower current? lower current or higher current or the same current
(a) Calculate the resistance per unit length of a 44 gauge nichrome wire of radius 0.642 mm.
(b) If a potential difference of 12.0 V is maintained across a 1.00 m length of wire, what is the current in the wire?
(c) The wire is melted down and recast with triple its original length. Find the new resistance R N as a multiple of the old resistance R O .
(d) What is the resistance of a 5.4 m length of nichrome wire that has a radius of 0.321 mm? How much current does it carry when connected to a 120 V source?
