Potential drop when current flows through a resistor

  1. May 18, 2013 #1
    What is the reason for the potential drop when current flows through a resistor? Is it due to conversion of potential energy of the electrons into thermal energy while flowing through the resistor?

    The "volt" has units of joules/coulomb, and the joule is a unit of work. So, yes, in a resistance electrical energy is being converted into thermal energy.
