Low Voltage

Is this accurate?

I was always under the impression for most loads if voltage drops amperage increases.

The load has not changed therefore Voltage drops, current drops.

Most loads are constant impedance so if voltage drops so does current.

Some loads like DC power supplies are constant power, so if voltage goes down, current goes up.

Some loads are constant current loads, but these are rare in the hobby.

For the modern reef aquarium I can think of only one resistive load..

Even in my home I can think of only one resistive load unless my gf is drying her hair..

Heater, cooling fan, AC return pump, chiller, magnetic ballasts for MH, non-led lighting

Regulated DC power supplies or electronic ballasts make more modern pumps, lights, etc turn into constant power loads.
