(1) Two glasses of water are connected in parallel and ammeters are connected in series. Measure the current of two glasses of water respectively. The
(1) Two glasses of water are connected in parallel and ammeters are connected in series. Measure the current of two glasses of water respectively. The circuit diagram is shown in the figure.
(2) In order to ensure the scientific nature of the experiment, he used two identical devices to take tap water and Chen Jiangshui with the same quality.
(3) In order to prevent short circuit, the switch should be in the off state in the process of connecting the circuit; The sliding rheostat should be at the A end in the drawing.
(4) It was found in the experiment that the indication of ammeter A was greater than that of current B, from which he judged that Chen Jiang was polluted.
(5) Reasonable suggestions for protecting water bodies in Chen Jiang: Sewage can be discharged up to standard after treatment; Develop civilized habits and don't throw rubbish into the river.
So the answer is: (1) as shown in the figure; (2) equality; (3) disconnect; a； (4) greater than; (5) Sewage can be discharged up to standard after treatment.
