All coils are different. They can be anywhere from 3000 to 8000 ohms.
Absolutely. One coil’s secondary winding may have more / fewer turns of smaller / larger-gauge wire than another, and still achieve the same basic results. Resistances can vary widely between otherwise similar designs – and temperature also plays a role.
Of course, if you have two ‘identical’ coils, they should measure within a few percent of one another – and really, that’s about your best guide, unless the mfr. is so kind as to provide resistance tables.
