Dear Sir/Madam,
I connect a PN2222A NPN transistor and a variable resistor at 1K, the motor on but the transistor is very hot. I think I need to replace another model transistor but I have no idea which model should be chosen when I reading the datasheet, which information I should focus? Can anyone suggest me the model of the transistor with an explanation by the figure from datasheet?
Should I need to replace 1K resistor with other resistance if I change the transistor, how much I need? How do I calculate the resistance need?
Best regards,
Kelvin.
