What is the heating rate of the electric heating wire in the hair dryer

In theory, the resistance value of the electric heating wire of my point blower is reduced, which may cause the heating degree of the electric heating wire to be higher than that of the broken one. The power is increased by half, and it can be connected to the same one as in

Is the electric heating wire of hair dryer made of material with lower melting point

Fe Cr Al alloy and Ni Cr alloy wires are two kinds of electric furnace wires. The former belongs to the alloy material with ferrite structure, while the latter belongs to the alloy material with austenite structure. In addition, there are some special electric heating alloy wires, such as tungsten wire and molybdenum wire
Non low melting point material. High melting point material

The experiment about electric power
There are the following materials on the experimental table: constant voltage 6V power supply, ammeter, voltmeter (0 ~ 15 range is broken), sliding rheostat, switch, a number of wires. Requirements: using the above equipment, design an experimental scheme to measure the rated electric power of 3.8V. (draw the circuit diagram) [can think of a way to draw better]
I need it in a hurry

Just connect the voltmeter in parallel to both ends of the sliding rheostat
Principle: adjust the sliding rheostat so that the voltage indication is 2.2V, then the voltage at both ends of the small bulb is 6v-2.2v = 3.8V, so that the rated voltage can be achieved and the voltmeter can measure
I wish you progress in your study!

Urgently seek the experiment problem of measuring resistance and electric power?

(2010. Suqian) as shown in Figure C, it is a circuit for measuring the electric power of a small light bulb (2.5V 0.3A). Please connect the physical circuit completely. Answer: 28. (2010. Ningbo) in the experiment of "measuring the electric power of a small light bulb", the selected equipment includes a 6V power supply, a small light bulb with a rated voltage of 2.5V, and
