Here you can examine a resistor in a frequency simulator. In addition to the resistance, a resistor also has an internal capacitance and inductance. These characteristics appear more clearly in constructions that work at high frequencies.
During the dimensioning process, you can choose to download a standard type and enter the resistance and any component leg data, or you can enter all parameters manually. The impedance ratio of the component can be studied in a frequency graph. This tells you what impedance a component has at a certain frequency. It is particularly interesting to test a resistor in the impedance graph, the rated resistance of a resistor can for a certain frequency be completely different.
