Hi,
While I am watching this video of GreatScott! **At 3:21

I took up my calculator and calculate the power by using P=(V^2)/R, and the answer is 72W.
- This happens due to the voltage across the Peltier may not be accurately 12V as there's Req=Rpeltier+Rwire, is my statement correct?
- 72W and 32W is totally a huge difference, why?
- So, when to use P=(I^2)R and P=(V^2)/R to calculate power loss?
Thanks in advanced.
Jay
