Summing Sine Waves with Phase Offset

[@enkeleen]

Thank you Merlijn. You are a master educator and a gift to the industry. All the best.

Gracias Merlijn, siempre pendiente de tu canal. Saludos desde Colombia

you are my best inspirator ever merlin .thanks so much

Are these numbers only true when the sine waves combined are 1 decibel? If the sine waves are 10 decibels do you get 50, 30, -60 decibels or are two 10 decibel sinewaves combined in pefect phase to become 16 decibels?

I'm curious why two 120V legs of 208V 3 phase system, separated by 120º, sum to 208V instead of 120V as this calculator indicates? Anyone know why that is?

[@MerlijnvanVeen]

Excellent question! Sound pressure is about summation. Whereas three‑phase electric power considers the - difference - between phases, i.e., subtraction. I posted an illustration here: facebook.com/merlijn.vanveen/posts/1028349245335764

Hi Merlin! In about 13 minuts you talk about L1, L2 and L3 phases of an AC generator. In this case the circuit is a summing circuit or an push pull circuit? Thank you!

Thanks, Merlijn you made great tool, but can you tell us where we can use this tool in best ways?

[@CyrilleBoucanogh]

Oh, thank you so much!!!

[@nicolesowers9224]

I really like this! How did you make this in excel?

[@deniocosta]

Curiosity: "In time but out of phase". Can I say: "In phase but out of time"? Thanks again!

[@MerlijnvanVeen]

Denio Costa yes, both are possible. All the best to you and your loved ones!

Thanks!!!
