While the repair shop works on your voltmeter, they loan you anunusual replacement: Rather than measuring the potential difference across a resistor, it measures the amount of charge that flowed,and the change in electric potential energy of that charge. You usethe device on a resistor and it tells you that 2.5 C of chargeflowed through it, and that the electric potential energy of thatcharge decreased by 0.40 J. What is the potential difference across the resistor? (Report the answer as a positive number.)
