Question:

Each end of a wire is connected with two copper wires, and then connected with a small range ammeter to form a closed circuit

Each end of a wire is connected with two copper wires, and then connected with a small range ammeter to form a closed circuit

Answer:

Because the temperature difference between two points can reach 1700 degrees centigrade, the measurement range is large, and the mercury thermometer can not measure the high temperatureThe answer is: (1) increasing; (2) inside; (3) measuring range
As can be seen from the table, the temperature of the current in the thermocouple circuit will increase as the temperature difference between the two contacts increases;
According to the data in the table, the greater the temperature difference, the greater the current in the circuit, indicating that the thermocouple is the internal energy into electrical energy devices;
