The formula to find $${\text{I}}$$ when the values of V and R are known is
A. $${\text{I}} = {\text{VR}}$$
B. $${\text{I}} = \frac{{\text{R}}}{{\text{V}}}$$
C. $${\text{V}} = {\text{IR}}$$
D. $${\text{I}} = \frac{{\text{V}}}{{\text{R}}}$$
Answer: Option D
Since the formula is V=IR (ohms law).
And if R and V are known so the equation will become to find the I is
I = V/R
So the correct answer is D
