In [3]:
#Given
Vp=8                       #volts
R=75                       #Ohm

#Calculation
Vmax=0.707*Vp
P=Vmax**2/R

#Result
print"Power is dissipated in the load is ",round(P,4),"Watt"

Power is dissipated in the load is  0.4265 Watt

In [8]:
#Given
Pf=380.0                     #Watt
Pr=40                      #Watt

#Calculation
import math
m=math.sqrt(Pr/Pf)
SWR=(1+m)/(1-m)
print"SWR= ",round(SWR,2)

SWR=  1.96
