Another "Will this work?" question asked by me.
The question is..
Will 75Ω resistor be fine for my experiment?
My radio's specifications are 3.0V, 0.14 A (based on my multimeter's reading) I guess it was 148 milliamps.
I used the formula given by SgtWookie. And found out that the resistor I need is 77.428571428 . I chose 75Ω because it is the closest among 68 and 82Ω.
Anyway, I am not about of wasting the power. I just want to see if it will work or not.
P.S. My power source will be 13.8 V .
Formula
Rlimit = Vsupply - (LED*numbers in series) / Ampere
13.8V 3.0V * 1 0.14
13.8V 3.0V 0.14
10.8V/0.14A
=77.428571428 OR 75Ω
Final question: Will radio work with 13.8 V battery with 75 ohms connected?
thanks and pls. answer if it will work.
any help will be appreciated.
