Answer:

2 ohms

Explanation:

Hi there!

Ohm's law states that V=IR 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

V=IR\\15=(7.5)R

Divide both sides by 7.5 to isolate R

\frac{15}{7.5}= \frac{7.5R}{7.5}  \\2=R

Therefore, the circuit resistance would be 2 ohms.

I hope this helps!

Which of the following describes the electron sharing between hydrogen and fluorine A.Hydrogen and fluorine share one electron w
atroni [7]
Hydrogen has one electron in its outermost shell, while fluorine has seven electron in its outermost shell, hence both hydrogen and fluorine needs a single electron to complete its outermost shell. 
That's why there is a single bond between hydrogen and fluorine.
Hence both hydrogen and fluorine share one electron with each other, so option "A" is correct.
