Calculating resistance, voltage, and current using Ohm's law


A student builds a simple circuit with a single resistor with resistance 2R and measures an electric potential difference ΔV across the resistor. Then, the student replaces the resistor with a new one of resistance R2 and keeps the electric potential difference the same.
What is the current I2 through the new circuit in terms of the original current, I1?
