Which equation expresses Ohm's Law?

Explanation:
Voltage, current, and resistance are linked linearly by Ohm's Law: the voltage across a conductor equals the current through it multiplied by its resistance. With E representing voltage, I the current, and R the resistance, the direct expression is E = I × R. This form clearly shows how changing current or resistance affects the voltage needed. While you can rearrange the equation to I = E / R (which is also true), the form E = I × R is the straightforward, standard way to express the relationship with these variables.
