Concept #1: Resistance and Ohm's Law

Concept #2: Resistivity & Resistors in Circuits

Practice: A resistor has a current through it of 5 A. If the EMF across the resistor is 10 V, what is the resistance of this resistor?

Example #1: Current Through Unknown Resistor

Practice: Two resistors are made of the same material, one twice as long as the other. If the current through the shorter resistor is 5 A, what is the current through the longer resistor if they both have the same potential difference?
