How To Choose A Pull-up Resistor Value

I recently got a question about choosing a pull-up resistor value: Hey!In Monostable button triggered circuit, why did you connect 10 kΩ specifically? Does it contain any calculations? You can use resistors for many things. In the following 555 timer circuit that he was referring to, the resistor R2 is a pull-up resistor with a […]

Current Limiting Resistor

A current limiting resistor is a resistor that is used to reduce the current in a circuit. A simple example is a resistor in series with an LED. You would usually want to have a current limiting resistor in series with your LED so that you can control the amount of current through the LED. […]
