FAQ:

Q: How to stepdown 12V to 3V using resistor?

A: Our task is to stepdown 12v into 3v. so, we are going to use 1k ohm resistor and 330-ohm resistor. Connect one end of 1K ohm resistor to 12v supply and second to any other hole of breadboard.

Q: What is a 12V divider circuit?

A: 12v battery x 1 multimeter x 1 A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input.

Q: How do I connect a 1K ohm resistor to a 12V supply?

A: Connect one end of 1K ohm resistor to 12v supply and second to any other hole of breadboard. Frome same hole connects one end of 330-ohm resistance and another end to the ground.
