<p>A current of 1 A flows in a series circuit containing an electric lamp and a conductor of 5<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;when connected to a 10V battery. Calculate the resistance of the electric lamp. Now if a resistance of 10<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;is connected in parallel with this series combination, what change (if any) in current flowing through 5<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;conductor and potential difference across the lamp will take place? Give reason.</p>
