How do you know what size resistor to use?
A rule of thumb is to find a resistor with twice the power rating. Here I would choose a 250 mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.
How can I reduce 12vdc to 9vdc?
To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V – 9V = 3V) to determine the total amount of resistance needed.
What resistor do I need to drop 24V to 12v?
Registered. The resistor you need is 120 ohm power rated at 2W, that is the most common value I would use.
What resistor do I need to drop 12v to 3v?
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.
How do I choose the right resistor?
Resistor selection requires three steps:
- Determine the resistance and the watts to be dissipated by the resistor.
- Determine the proper “Watt Size” (physical size) as controlled by watts, volts, permissible temperatures, mounting conditions and circuit conditions.
What resistor do I need to drop 12v to 6v?
It’s possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit.
What resistor do I need to drop 12v to 5V?
12v to 5v converter using a voltage divider: Components required: One 12v battery, 1.8k resistor, 1.3k resistor, connecting wires.
How do I step down 24Vdc to 12Vdc?
We often get asked “How do you reduce 24Vdc to 12Vdc” and the answer is pretty easy – you use a DC to DC converter which has a 24Vdc (nominal) input with a regulated 12Vdc output. If you have a requirement for converting any DC voltage to any other DC voltage then please do get in touch!
