Chapter 6:Series Circuits

Problem no:6.1, Page no:54

In [1]:
#Cal of Resistance

#Initialization

#Resistances in ohm connected in series

R1=5

R2=5

R3=5

#Calculation

R=R1+R2+R3                        #Formula for series resistors

print "The Equivalent resistance is",R,"ohm"
The Equivalent resistance is 15 ohm

Problem no:6.7, Page no:57

In [2]:
#Cal of Current

#initialization

V_emf=1.5                          #Voltage in V

R=0.4                              #Resistance in Ohm

r=0.05                             #internal resistance in Ohm

#Calculation

I=V_emf/(R+r)                      #Formula for current with emf and internal resistance

print "The Current in the circuit is",round(I,2),"A"
The Current in the circuit is 3.33 A
