R1 | R2 | V |
10K (0.5w) | 39K (2w) | 23.88V @ 60mA |
4k7 (2w) | 3k3 (1w) | 12.38V @ 70mA |
10K (5w) | 2K2 (2w) | 5V @ 180mA |
... and bob's-your-uncle as they say however a friend of mind pointed out that it might not be good since a fan is inductive not resistive...
The two resistors are no "15V" generators. They just divide the input voltage by 2.Something like so? So the resistors are just a 15v potential divider that are turning on the transistors but what limits it to 15v?
