Question #238921

A single layer of No. 24 WGA (dia=0.0201) commercial iron wire is wound over a ceramic tube whose diameter is 3.25 in if the total wire resistance is 41 ohms, determine the number of turns.

Expert's answer

Solution

Given data

Diameter (d)=0.0201 in

Resistance (R)=41

Circumference of ceramic tube(c)

= =1turn

And CM=

Resistance

No. of turns

Therefore number of turns are 260.
