A voltmeter connected to the terminals of a power source with an electromotive force (EMF) of $12 \mathrm{~V}$ shows a voltage of $U=9 \mathrm{~V}$. Another voltmeter of the same type is connected to the terminals of the source. Determine the readings of the voltmeters. (The resistance of the source is nonzero, and the resistance of the voltmeters is finite).
