How many watts are in 100 2.5 volt bulbs?
This question does is not answerable. A watt is a volt times an amp. With out knowing how many amps the bulbs use there is no answer.
Your car door shocks you when you touch it?
It's called static electricity. The 12 volt system in cars and trucks are not enough to shock someone. Even 24 volt systems found in buses and heavy trucks are not enough to feel. So it has to be static electricity somehow.
How Convert 200 volt to 230 volt?
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
How many cells does a 12 volt battery have and what is the capacity of each cell?
Typically 6 cells at approximately 2 volts per cell. The cell voltage varies by the chemicals used to make the cell (lithium would be around 3v for instance) To charge a typical 12V battery it's common to use 13.4V to 13.8V http://en.wikipedia.org/wiki/Lead-acid_battery
Can a 12 volt battery safely run a 9 volt motor?
Running a 9 volt Motor on a 12 volt BatteryUsually, I have gotten away with this, BUT... depending on the quality of the windings in the motor, it could burn through the tiny wire in the motor winding. I have done this many times with no problem, but have also burned out a few motors.One good example is that I have several [from the "early" days] cordless drills. The early ones used anywhere from 6 to 9 volt battery packs.I then bought a 12 volt drill at Harbor Freight and Tools, and when I got it home and examined it I realized that the 12 volt battery pack was IDENTICAL in size to the older 6 and 9 volt packs.So, after charging the new 12 volt pack, I tried it in the older 6 and 9 volt drills. Lo and behold, it worked fine, with just a little more RPM and drilling power.I then called my Electrical Engineer brother and asked him about it and he said that those small drill motors are not that sensitive to even a doubling of voltage and perform OK with 12 volts on 6 and 9 volt units.That was about 4 or 5 years ago, and for some time, I've been using 12 volt battery packs for all three units [6, 9, and 12 volts]. When time came to replace failed 6 and 9 volt units, I switched to 12 volt packs for all 3 drills.Again, I think 12 volts will be safe for your 9 volt motor, but it depends on the motor.
How many volt DC systems are used in a car?
Most cars use a 12 volt system. Most cars built before about 1956 used a 6 volt system. Some, very few, use a 24 volt system.
What are lighting systems that use low voltage used for?
Usually things like 'mood lighing' or concealed 'lighting'. They typically run iff a 120 volt suppply via a transformer.
How many volts is a tractor battery?
It depends on the age and size of the tractor. The older tractors were 6 volt systems. Newer more modern tractors are generally 12 volt systems. Large Horse power machines will probably have 24 volt systems.
Where are the positive and negative posts in a 48 volt system?
their are many many types of 48 volt systems you need to show or state more info on your system
Is a 1940 Chrysler 12 volt or 6 volt?
If that 1940 Chrysler is in original condition, it would have a 6 volt system. Originally, it was a 6-volt. However, many people convert them to 12-volt systems for convenience purposes.
In a normal 277 volt situation is there one hot leg or two?
277 volt systems aren't normail systems
Does the 1971 Volkswagen camper have a 6-Volt or 12-Volt Regulator?
1971s had 12-volt systems.
Which resistor is connect 1.5 volt led to series 220v ac?
Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.
Are auto electric systems 12 volt or 120 volt?
12 Volts DC
How many volts is a semi truck battery?
They're 12 volt systems, typically with four batteries wired in parallel, rather than series - this keeps the voltage at 12v, while making available the full amperage of all of the batteries.
How many voltage used in motherboard?
12 volt
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
