NINE VOLT BATTERY FULL

This is because the voltage of a LED is only a fraction of a volt, so a 9V battery can provide enough power to light up a 12V LED. Yes, a 12V LED can be powered by a 9V battery. That’s because the battery’s voltage is too high for the LED, and the resistor will help drop it down to the five volts the LED needs. The resistor will act to limit the current flowing through the LED, preventing it from being damaged.Īs well as that, If you want to connect a five-volt LED to a nine-volt battery, you’ll also need an external resistor. This is because the voltage drop across an LED is approximately two volts, which is lower than the voltage of a typical 9v battery. Yes, a five-volt LED can be connected to a nine-volt battery, but an external resistor is also needed in order to drop the voltage to the five volts required. Can A Led Be Connected Directly To A 9V Battery?Ĭan an LED be connected directly to a 9v battery? This is because lower voltages mean that less current will flow, and too many LEDs in series would require too much current, which would damage the battery. Moreover, This means that if you want to use LEDs with a 9 volt battery, you can only have two of them in a row.

Therefore, if you have more than two LEDs, you will need to add more batteries in order to provide the full current. This is because you need to ensure full current over a reasonable range of battery voltages – 9.5 V down to 8 V. You can only have two LEDs in series on a 9V supply.
