Review Аавьсера Аавьсера Аавьс давbcat Аав да 1 Normal 1 No Spac. Heading 1 Heading 2 Title Paragraph Styles Using python.... 1. Given DC voltage, 50 V and set of resistance 100 to 300 in steps of 52, (1) calculate the currents and (2) the power dissipated in the resistors. (3) plot a current vs resistance. (4) write Resistance, Current, Power to a text file. (Do these on the console) Write a program that will perform (1) - (3) in (a) for any set of resistance and DC voltage. Validate your program with (a). o BI E

Answer 1

PYTHON PROGRAM

FORMULA:

Current= Voltage/Resistance

Power=Voltage*Current

The explanation of the program is given as comments in grey and italic.

#To draw the Graph
import matplotlib.pyplot as plt
#Voltage=50 (Given)
voltage=50
#List to hold all the values
currents=[]
powers=[]
resistances=[]
print("Resistance\tCurrent \tPower" )
# Resistance starts from 10 and moves till 30 in increments of 5
for resistance in range(10,31,5):
    #Append the resistance value to resistances list
    resistances.append(resistance)
    #Calculate current for this resistance 
    current=voltage/resistance
    #Append the current value to currents list
    currents.append(current)
    #Calculate power
    power=voltage*current
    # Append the power value to powers list
    powers.append(power)
    #Print the answer in console
    print(resistance,"\t\t",current,"\t\t",power)
#Plot the graph for currents list in x axis and corresponding resistance in y axis
plt.plot(currents,resistances)
plt.xlabel("Current")
plt.ylabel("Resistance")
plt.title("Current Vs Resistance")
plt.show()
