From I=UR, it can be seen that the circuit current becomes smaller and the indication of ammeter A becomes smaller;
(2) the ratio of voltmeter V 1 to voltmeter V2 UV1uv2 = IR1ir2 = r1r2, because when the slider p of the sliding rheostat moves to the right.
The resistance R 1 remains unchanged, and the resistance R2 becomes larger, so the ratio becomes smaller.
So the answer is: smaller; Get smaller.
