8. A +2μC charge moves between two positions in an electric field. If it had been +4uC instead, it would have traveled through the same voltage, but the system's potential energy change would double. 9. Four point charges are placed at the corners of a square as shown. If they all have the same amount of charge then the electric potential and electric field at the center is zero. -Q K +Q 10. The voltage between the plates of a charged capacitor is measured. The voltage between the places decreases and the capacitance increases if a dielectric is inserted between the plates. L 11. The electric field inside a conducting wire is directed left. Electrons in the wire drift left, which causes a conventional current to flow right. 12. The resistance of a device is measured at an initial temperature. If the experiment was repeated at a higher temperature then the resistance of the device would be smaller. ㅅ 13. An AC electric generator creates a time varying current in a circuit. The rms voltage of the generator is larger than the peak voltage. 14. The unit kilowatt-hour is a measurement of power. 8.
