+# tusistor
+
+This is a [Ratatui] app to calculate the color codes and specs of electrical resistors.  
+3, 4, 5 and 6 band resistors are supported.  
+You can go from selected color codes to specs or from specs to color codes.  
+The resistance input supports the RKM notation, e.g. `4k7`.  
+The input of tolerance and/or TCR are optional depending on your resistance input.
