V = I * R here you have V = 9 = I*R = 3*R, hence R = 3. Your answer is A.

Ohms regulation states that: Voltage = modern greater by way of Resistance V = Voltage I = modern R = Resistance So V= IR subsequently: R = V divided by way of I R = V/I R = 9V/3A = 3ohms. it fairly is in all probability the 1st formula on the 1st website of any elementary circuits e book.
