+ | ===== Resistor ===== | ||
+ | The easiest component to start with is the resistor. | ||
- | ======= Questions | + | Resistors have many usage: |
+ | <WRAP indent> | ||
+ | <<In electronic circuits, resistors are used to reduce current flow, adjust signal levels, divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat [...] or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, | ||
