Have you ever wondered what made car manufacturers decide to go from dynamos to alternators for generating electricity? It's a mix of reliability and cost.

Modern automotive alternators have a voltage regulator built into them. Typical car alternators generate the field using a DC current through slip rings. The field current is much smaller than the ...

Electromagnetic induction has wide-ranging applications, most notably in both AC and DC generators, and in the transmission of electrical power through transformers. In the previous section, Faraday’s ...
