AAAA (not available for retail sale,) AAA, AA, C, D, or almost any button cell battery are 1.5V each (use 8.) Large batteries, usually found in flashlights are 6V (use 2.) Car batteries are 12V (use 1.) Never mix more than one battery type in a single power source.
This will still only produce 12 volts. It will produce 1200 watts. watts is the result of Volts times Amps.
Your car should produce about 14.4 volts from the alternator when the engine is running. If it does not produce anything over 12 volts, your alternator is not charging and you need to get it repaired or replaced.
If you are looking for a power inverter then you are going to need to take a number of things into account. These power inverters are not all equal, and they will vary in price and functionality. This blog will look at how you can narrow down your search to the right power inverter for your needs.
Yes. If you have a device rated at 12 Volts and 150 milliamps, you can use any power supply that will deliver at least 150 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 150ma that it needs.
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
6 amps.
12 volts
Step up transformer.
Yes, you can plug in a 12 volt pump to a 400 watt inverter as long as the pump's power requirements do not exceed 400 watts. Make sure the inverter is designed to convert 12 volts DC to 120 volts AC to power the pump effectively.
A 12 volt battery supply a 12 VDC potential to a 12 VDC load.
Neither amperes nor volts is the same as watts (power), so the question "what is the higher power" does not make sense.Amperes is electrical current flow, in coulombs per second.Volts is electrical potential, in joules per coulomb.Watts is electrical power, in joules per second, which is also amperes times volts.
The device consumes 84 watts of power. This can be calculated by multiplying the voltage (12 volts) by the current (7 amps). So, 12 volts x 7 amps = 84 watts.
