Technically, dimmers depend
on the type of lights or loads 1/3
● Technically, dimmers depend on the type of lights or
loads
● Ohmic loads: incandescent lights, bulbs or 230 V AC

R
● Inductive loads: Low voltage halogen lights with
ferromagnetic transformers or some fluorescent tubes
(linear or lamp) with ferromagnetic transformers
● Capacitive loads: Low voltage halogen lights with
electronic transformers
L
