How does Liquid resistance starter works? - Quora
Answer: An electric motor typically takes 6 to 8 times more current to get it running than to keep it running at full load. So resistors are sometimes used to reduce that inrush current so the electricity supply can cope with the short term high load and other users are not inconvenienced by a lo...
