Conclusion. An inductive distributor is a mechanical device that is used to distribute high voltage electrical energy from the ignition coil to the spark plugs in older vehicles. While it is a relatively simple and reliable design, it does have some disadvantages, such as its lack of precision and limited ability to deliver high voltage.
