Sep 27, 2016 · 6V to 12V DC Converter Circuit. The 6V to 12V DC Converter Circuit mainly includes DC to AC conversion, AC to DC conversion which is discussed below. DC to AC Conversion. In many of the applications it is required to convert from DC to AC. This is mainly used in places like camping, on roads where Stereo or TV is used or other appliances are ...
Feb 08, 2017 · If I wish to drive a 3V LED at 20 mA from a 12V battery, I can use a dropper resistor. I subtract the LED's forward voltage from the 12V to get 9V, and divide this by the 20 mA, to get the value of resistor needed. R=V/I = 9/0.02 = 450 ohm.
through the USB cable, also has an on-board voltage regulator that outputs 3.3V. If you need less than 5V for a project, you can use the 3V3 pin, Which provides about 3.3V. The current draw from the 3V3 pin is limited to 50mA. max power = V·I = 3.3V·0.05A = 0.165W = 165mW

May 02, 2020 · Is it 12V? Anyway you can drop the voltage by using the last concept explained above, or you can also use an LM338 IC variable voltage regulator to adjust the output to 3V. Resistor divider will not work, because resistors will waste a lot of power and also will not be able to provide sufficient current to the motor.
