Lesson 1: Electric current, resistivity, and Ohm's lawCalculating resistance, voltage, and current using Ohm's law
Problem
A student builds a simple circuit with a single resistor with resistance and measures an electric potential difference across the resistor. Then, the student replaces the resistor with a new one of resistance and keeps the electric potential difference the same.
What is the current through the new circuit in terms of the original current, ?
