Can a current be limited in PCB circuit?

I was interested in circuits in all kinds of electronic components? A strange idea that comes to my mind recently, is the ballast resistor can be used to limit a current in a PCB circuit?
If yes, what is the example in our daily life? Can you share your ideas?

Capacitive Proximity Sensing Technology in Smartphones

Infrared (IR) proximity sensors are currently widely used in smartphones to prevent accidental touches on the touch screen caused by the user's face during a call while reducing power consumption. The IR sensor has the advantages of long detection distance and fast response speed, but its expensive ...

Is it true that turned off PCs get older/broken if its turned off for too long?

:D Thanks to technology I became more paranoid every day, is it true that turned-off computers can get older in terms of lifespan or gets a break in some way if they are stay turned off for too long time? I always thought the dust and overheating are the enemies. I've seen this saying "The Best" cap...
