Question about electric field

  1. Feb 26, 2015 #1
    We all know that wherever there is potential difference in space, there will be electric field there. So if we set a power supply to output 1V, but we connect the two leads to nothing, just leave them in air, the ends of the two leads have a potential difference of 1V, there will be a electric field produced between the two ends. My question is if we connect the two leads to a resistor, will the electric field be different from without a resistor?Will the electric field in this case only exists inside the resistor?
