To find the potential difference across the capacitor as it discharges through a resistor, you can use the formula for the charging or discharging of a capacitor in an RC circuit:
V(t) = V0 * e^(-t / RC)
Where:
  • V(t) is the potential difference across the capacitor at time t.
  • V0 is the initial potential difference (charged voltage), which is 10 volts in this case.
  • t is the time in seconds, which is 3 seconds in this case.
  • R is the resistance in ohms, which is 1 megaohm (1,000,000 ohms).
  • C is the capacitance in farads, which is 3 microfarads (3 x 10^(-6) farads).
  • So the answer is approx 3.8V (3.769V
  • )
