Resistors have the function of storing energy

How does a resistor work?

A resistor works by converting electrical energy into heat, which is dissipated into the air. What is resistance? Electricity flows through a material carried by electrons, tiny charged particles inside atoms. Broadly speaking, materials that conduct electricity well are ones that allow electrons to flow freely through them.

Do resistors transform electrical energy to heat?

Yes, resistors will transform electrical energy to heat, which is considered "internal", however, you will not find many treatments of electrical circuits in terms of thermodynamics. The reason for that is because electrical circuits are extremely far away from thermal equilibrium and thermodynamics has very little useful things to say about that.

Why are resistors important?

Resistors come under passive electronic components and are extensively used in electronic circuits. So important are these components that it may be virtually impossible to build an electronic circuit without involving resistors.

How is a resistor used in a circuit?

A resistor is used in a circuit to limit current flow. It is analogous to a bottleneck in a water pipe. Its resistance (R) is measured in ohms – and here are some of its common functions: Limits current flow. Used with other resistors to split up voltage or current to useful levels (like in voltage or current dividers).

What happens when a current flows through a resistor?

When a current flows through a resistor, electrical energy is converted into HEAT energy. The heat generated in the components of a circuit, all of which possess at least some resistance, is dissipated into the air around the components. The rate at which the heat is dissipated is called POWER, given the letter P and measured in units of Watts (W).

What is the function of a resistor on a cooktop?

A common electric cooktop burner is a resistor. When voltage is applied to it, it gets hot and dissipates heat, providing the heat source for cooking. In this case, the resistor is used to take some of the power generated at the source and outputs it in the form of heat on your cooktop.
