# Chapter 10 Thermoelectric effect¶

## Example 10.1 Page no 304¶

In [3]:
#Given
a=15                              #degree C
b=270

#Calculation
c=(2*b)-a

#Result
print"Temperature is", c,"degree C"

Temperature is 525 degree C


## Example 10.2 Page no 304¶

In [6]:
#Given
a=10                         #degree C
a1=527

#Calculation
a2=(a+a1)/2.0
print"Temperature is",a2,"degree C"

Temperature is 268.5 degree C


## Example 10.3 Page no 304¶

In [8]:
#Given
R=100                       #ohm
I=10**-6                     #A
E=40.0*10**-6                   #V

#Calculaton
e=R*I
t=e/E

#Result
print"Smallest temperature difference is",t,"degree C"

Smallest temperature difference is 2.5 degree C


## Example 10.4 Page no 304¶

In [13]:
#Given
a=80                    #Degree C
b=13.31                 #micro V degree/C
B=-0.038                 #micro V degree/C**2

#Calculation
E=(b*a)+((B*a**2)/2.0)
an=-b/B

#Result
print"Thermo emf of silver is",E,"micro V"
print"Neutral temperature is",round(an,2),"degree C"

Thermo emf of silver is 943.2 micro V
Neutarl temperature is 350.26 degree C


## Example 10.5 Page no 304¶

In [16]:
#Given
a=14                         #micro V degree/C
b=-0.04                      #micro V degree/C**2

#Calculation
an=-a/b

#Result
print"Neutral temperature is",an,"degree C"

Neutral temperature is 350.0 degree C


## Example 10.6 Page no 304¶

In [24]:
#Given
E=500                         #micro V
a=41                         #micro V degree/C
b=0.041                         #micro V degree/C**2
c=-5500

#Calculation
import math
A=-(a+(math.sqrt(a**2-4*b*c)))/(2.0*b)

#Result
print"Temperature of hot junction is", round(A,2),"degree C"

Temperature of hot junction is -1119.8 degree C
