Answer :
to find the resistance, the formula you need to use is
[tex]r = \frac{v}{i} [/tex]
whereby i reprsents the current and v represents the potential difference.
therefore,
r=63/7
r=9 ohms
[tex]r = \frac{v}{i} [/tex]
whereby i reprsents the current and v represents the potential difference.
therefore,
