Answer:

1. It is entirely possible that different devices will have different efficiencies, and will therefore produce a different amount of heat - It is entirely possible that different devices will have different efficiencies, and will therefore produce a different amount of heat.
2. The heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element.
3. Electric Heater is a device that can convert Electric energy into heat energy.

Answer:

⭐ Here's the answer hoping it helps!

Explanation:

1. It is entirely possible that different devices will have different efficiencies, and will therefore produce a different amount of heat - it all depends what fraction of the electrical energy coming in is being converted to the other types of output.

2. When a thermoelectric material is exposed to a temperature gradient — for example, one end is heated, while the other is cooled — electrons in that material start to flow from the hot end to the cold end, generating an electric current.
