What is the formula for resistance using voltage and current?

Explanation:
Ohm’s law ties together voltage, current, and resistance. V = I R means voltage equals current times resistance, so solving for resistance gives R = V / I. This uses the same two quantities the question mentions—voltage and current—and yields the resistance in ohms (volts per ampere). The other forms don’t represent resistance: I/V would give conductance (how easily current flows), V × I equals power, and P/I simplifies to V again, not resistance. So the correct expression is voltage divided by current.
