I'm trying to nail down predictive voltage equations for three types of circuits used in low voltage outdoor lighting. I'm using this info for an article to be published in landscaping magazines.
They are :
1. The daisy chain method (lighting fixtures spliced at intervals along a single wire with one end connected to the power supply),
2. The daisy loop method (lighting fixtures spliced at intervals along a single wire with both ends connected to the power supply),
3. The t-loop method (lighting fixtures spliced at intervals along a single wire with both ends connected to a wire running to the power supply)
Knowing the output voltage of the transformer (12V), the resistance/ft of the wire, the distances of the wire runs between splice points and the wattages of each fixture I'm trying to determine the voltage at each fixture lamp.
Please understand that I'm not doing this for profit, so don't think I'm trying to get something for nothing. My invitation is for someone who sees this as a fun challenge and as a way to help improve how landscape lighting installers wire their projects.
Also, if someone could get these equations rights and put them into an excel worksheet, I'd be willing to pay for that.
Thanks.
