Answer:

2 ohms

Explanation:

Hi there!

Ohm's law states that [tex]V=IR[/tex] where V is the voltage, I is the current and R is the resistance.

Plug in the given information (I=7.5, V=15) and solve for R

[tex]V=IR\\15=(7.5)R[/tex]

Divide both sides by 7.5 to isolate R

[tex]\frac{15}{7.5}= \frac{7.5R}{7.5} \\2=R[/tex]

Therefore, the circuit resistance would be 2 ohms.

I hope this helps!
