How do you convert 6V to 3V?

from a 50amp supply at 5 volts you’d need a dropping resistor to drop 6–3 =3 volts at 50amps. You’d need a resistor of (R=V/I) – 3/50=0.06 ohms, not an easy value to get or make. And the power (Watts) is V x I =3 x 50 = 150 watts. This is totally wasted power.

How do you get 3V out of a 9 volt battery?

To reduce a 9V battery to 3.3 volts, use a zener diode, such as a 1N746 or a 1N4728A. Choose the appropriate one based on how much power it can dissipate. A 1N4728A has a 3.3-volt and a 1 W power rating. It can supply, on average, a stable 3.3 volts to a circuit or another component.

How do I reduce 3V to 1.5 V?

It depends upon how stiff voltage source (of 1.2V) you want to generate by voltage divider principle using resistors. In voltage divider circuit you want to drop 3.8V across R1 to get Vout = 1.5V. This can be done by n number of combinations of R1 & R2 values.

How do I reduce 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. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.

How can we reduce 12V to 3V by simply using a resistor?

You can use voltage divider circuit. consider tow resistors R1 & R2 , where R2 will provide 3 V output. so voltage across R2 will be=(V/Rt)*R2, Rt=R1+R2; so 3=(12*R2)/(R1+R2);

How do I convert volts (V) to amps (a)?

Volts (V) to amps (A) calculator. Select calculation type, enter volts and watts or ohms and press the Calculate button to get amps: The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω):

How do you convert 5V to 3V using a resistor?

So back to our circuit, if we have 5 volts and want 3V from it, we use the formula above. If we use a 10KΩ as our R 1 resistor, plugging in the values, we get R 2 = (V) (R 1 )/ (V IN – V)= (3V) (10KΩ)/ (5V – 3V)= 15KΩ. So we can use a 15KΩ resistor as our R 2 resistor with the R 1 resistor being 10KΩ.

What is the difference between 5V and V CC?

The 5V is now 2.5V. V CC is split in half. You may not always want half the voltage, but you can get the voltage to any level you want choosing the appropriate resistor values for a voltage divider circuit. Maybe your circuit is running off of 5V, yet you want only 3V to feed into a particular circuit element.

How do you divide 5V in half?

To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors. At this point where the jumper wire is placed, the voltage will be one-half the value of the voltage supplying the circuit. The 5V is now 2.5V.
