What resistor do I need to drop 12V to 9V?

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.

How can I reduce 12vdc to 3vdc?

Originally Answered: How can we reduce 12V to 3V by simply using a resistor? In order to have 3V available for the load, a 9V drop needs to be dissipated elsewhere. If the load is X Ohms, the dissipating component needs to be 3X Ohms in series with the load.

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.

Can I use a resistor to lower dc voltage?

The short answer is “don’t do that.” The voltage dropped by a resistor is given by Ohm’s Law: V = I R. So if you know exactly how much current your device will draw, you could choose a resistor to drop exactly 7.5 V, and leave 4.5 V for your device, when that current is run through it.

How do I drop 12v to 10v?

1. To drop voltage from 12V to 10.5V using resistors then you can use 2 resistor in series.
2. R2/(R2+R1) × 12V = 10.5V.
3. Solving the equation gives:
4. R2=7×R1.
5. Therefore if you choose R1 to be 4.7kOhm, R2 wil be 33kOhms.

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 9v to 5v?

9v to 5v converter using a voltage divider: Components required: One 9v battery, 1.5k resistor, 1.2k resistor, some multicolor connecting wires. It is a simple voltage divider configuration.
