Hence, the correct answer is:
Option : a
a. 5.6 amps
Step-by-step explanation:
It is given that:
The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor.
This means that:
[tex]I\propto \dfrac{1}{R}[/tex]
Hence, we get the relation as:
[tex]\dfrac{I_1}{I_2}=\dfrac{R_2}{R_1}[/tex]
where [tex]R_1[/tex] is the resistance corresponding to the current [tex]I_1[/tex]
and [tex]R_2[/tex] is the resistance corresponding to the current [tex]I_2[/tex]
We have:
[tex]I_1=6\ ,\ R_1=722\ ,\ R_2=768[/tex]
Hence, we get:
[tex]\dfrac{6}{I_2}=\dfrac{768}{722}\\\\\\i.e.\\\\\\I_2=\dfrac{722\times 6}{768}\\\\\\I_2=5.6406\ amperes[/tex]
Hence, the answer is:
Option : a
