The cross sectional area of the wire is
8495.968 mil².
The number of watts for the device is 108.16 watts
What is power?
Given
Diameter of the wire = 104 mils
R = 0.04 Ohms
I = 52 A
The cross sectional area = πr²
where
r is the radius of the wire
r = d/2
r = 104/2 = 52 mils
A = πr²
= π(52)²
= 2704π
= 2704 * 3.142 = 8495.968 mil²
Power in electric systems is the rate at which energy is transferred or converted measured in watts, it equals voltage multiplied by current.
Power = I²R
where
I is current in ampere
R is resistance in ohms
P = 52² * 0.04
= 2704 * 0.04
= 108.16 watts
The number of watts for the device is 108.16 watts.
