LED Light Bulbs are based on light-emitting diodes; the most notable advantages of LED light bulbs over conventional light bulbs are LED light bulbs last upwards of 50,000 hours. Additionally, LED light bulbs consume very little electricity. They are also shatterproof, run cool to the touch, and contain no Mercury or hazardous substances.

What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
How hot will get 2 9v battery connected together?
Please do not try that, with new fresh batteries stream explosions sometimes result!!!!
Can a 9v battery power a xbox?
no
What is the battery life of a 9 volt battery on a 3.5 volt of a bulb?
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
What is the difference between the car battery and 9V alkaline battery?
A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.
Can you power 5 meter 12v led strips with a 9v battery?
They might burn but they would be very dim and the battery would last for a very short time. They are 12 volt lights therefore it will take 12 volts for them to burn at the level of brightness that they should.
If you have a 12point6V battery and a 9V receiver how can you work out which resistor is needed?
you better not. you need a 9V regulator for this, not a resistor!
How would you wire a buzzer with a Lightswitch 2 gold screw on the right and 1 green on the top left and a 9v Battery Snap and of course a Buzzer?
Black cables from Battery and buzzer to Lightswitch. Buzzer and Battery Red cables connected
Can a 9v charger be used in a 12 v battery?
No.
Is there such thing as a 9v battery the shape of an AAA one?
no
Where can you get a 9v battery for behringer ultra metal um300 pedal?
You can buy 9V batteries from almost any supermarket
What size of resistor is required to operate the LED from a 9V battery?
In order to determine what size of resistor is required to operate an LED from a 9V battery, first start by knowing the current and voltage required for the LED. That information is available in the LED's specifications. For discussion purposes, lets assume a typical LED at 2.5V and 50mW. The translates to a forward current of 20mA. Build a simple series circuit containing a 9V battery, a resistor of an as yet unknown value, and the LED. By Kirchoff's current law, the current in the LED is the same as the current in the resistor, which is also the same as the current in the battery. This is 20ma. By Kirchoff's voltage law, the voltage across the LED plus the voltage across the resistor equals the voltage across the battery. This is 6.5V. (9 - 2.5) By Ohm's law, resistance is voltage divided by current, so the resistor is 6.5 / 0.02, or 325 Ohms. The nearest standard value to that is 330 Ohms. Cross check the power through the resistor. Power is voltage times current, or 6.5V times 0.02A, or 0.13W. A half watt resistor is more than adequate for this job.
