# Can I use a 12V DC power supply on a 5V?

## Can I use a 12V DC power supply on a 5V?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc. Mostly it will get damaged.

### How do you step down from 12V to 5V voltage?

Connect 12 v to pin 1 ,pin 2 is the ground and pin3 gives 5v. Don’t want to use IC or not getting it,use a voltage divider using 2 resistors and you are done with it. Connect 12 v across the series combination of 4.7k ohm and 6.8k ohm(readily available standard ) resistor and take the output across 4.7k ohm.

What is DC 5V for?

DC 5V/2A, means that the input voltage, to recharge the battery is 5 volts of direct current. It has two outputs, one 2.1A USB (for tablets and Raspberry Pi and high-current devices, the other 1A USB for phones and smaller devices.

How do I convert 7805 to 12V to 5V?

The 7805 is used a lot in circuits with a minimum footprint required to convert their voltage from a higher level to 5V….Hardware Components.

S.no Component Qty
1. LM7805 5V Voltage Regulator 1
2. 10uF Capacitor 1
3. 1uF Capacitor 1
4. 12V Power Source 1

## Can I use 5V instead of 12V?

A 5V adaptor cannot drive a 12V device. Also, an adaptor of voltage higher than the device needed would damage your device.

### Can I use 12V adapter for 5V router?

4 Answers. You cannot use that adapter because it is outputting more voltage than the original (12v vs. The new adapter must have the same tip polarity.

Are Apple Chargers 5V?

An iPhone charger delivers 5 Watts (5 volts at 1000 mA).

Does a diode reduce voltage?

Diodes allow electricity to flow in only one direction, but a diode will only conduct electricity, when the supply reaches its threshold. The threshold for common silicon diodes is 0.6 volts. After each diode, the voltage can be seen to drop by 0.6 volts. In this way, diodes can be used to reduce voltage, in a circuit.

## What are the advantages of DC supply over AC supply?

Advantages of ac over dc: We all know that we got ac supply in our homes and we got this supply by transmitting ac over long distances. The ac is easy to generate than dc. It is cheaper to generate ac than dc. The ac generators have higher efficiency than dc. The loss of energy during transmission is negligible for ac.

### What is regulated DC power supply?

A regulated power supply is an embedded circuit; it converts unregulated AC (Alternating Current)into a constant DC. With the help of a rectifier it converts AC supply into DC.

What is DC 5V input?

What is DC 5V power supply? 5V power supplies (or 5 VDC power supplies) are one of the most common power supplies in use today. In general, a 5VDC output is obtained from a 50VAC or 240VAC input using a combination of transformers, diodes and transistors. Is 5V dc dangerous?

What does a capacitor do in a DC power supply?

Power conditioning. The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery.
