How do you reduce voltage from 9v to 5V?
9v to 5v converter using a voltage divider: You can connect two LEDs in series across the output of R2 resistor if you are using a 9volt battery as an input. Components required: One 9v battery, 1.5k resistor, 1.2k resistor, some multicolor connecting wires. It is a simple voltage divider configuration.
How do you reduce 9v to 3v?
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.
Can I use 9v adapter for 5V?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn. It could be however, that your adapter has an internal resistance causing the voltage to drop to ~5V, so it could work in this case, if the adapter can supply the needed current…
Can I charge a 9V battery with a 5V charger?
You would not be able to charge a 9V with a 5V source. You can still charge that battery till 5V but once you cross that current will start flowing from the battery back to the source.
What household items use a 9 volt battery?
A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.
What can you do with 9 volts?
9-Volt Battery Projects
- Make a Flashlight. Since 9-volt batteries have the positive and negative terminals on one end, it is possible to easily touch both terminals at once.
- Divide Water. No, not like Moses and the Red Sea.
- Make Your Own Batteries.
- Feel the Power.
Can I use 6V adapter for 5V?
You could convert the 6V adapter to 5V if you’re comfortable with electronic circuits. This can be accomplished by hooking up the output of the adapter to a simple 5V linear regulator, which will probably have a dropout of 200mA.
