What is the electrical current in the US?
120 volts 60 Hz AC
Is the voltage rating on a light bulb the rms value or peak value?
It's the RMS value. A 120 volt lamp (light bulb) is rated according to its RMS voltage. Just like appliances in the home are rated at 120 volts (like your fridge, microwave and toaster), or 220 volts (like your clothes dryer). Note that these appliances will have to stand up to the peak voltage on the AC line. Naturally. And the peak voltage on an AC line is 1.414 times the RMS value of voltage. That means in a 120 volt AC line (120 volts RMS), the peak value of the voltage will be 1.414 times the 120 volts, or right at about 170 voltspeak for each cycle.
What is effective voltage?
It is the 'as if' voltage in an AC circuit. Referred to as Vrms 120 volts in your house is Vrms, the effective voltage, 'as if' it were DC 120V, can do the same work. But 120VACrms is a sine wave with a peak voltage much higher than 120 volts.
What does kvac mean?
K = kilo = 1000's V = volts AC = alternating current So, 12 KVAC is 12,000 volts of alternating current
480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
Is a converter considered ac out put volts?
is an 120 volt ac converter that we are using for 12 volts considered AC output power.
Can you charge battery from ac?
No, it must be charged with a battery charger plugged into 120 volts AC which converts it to 12 volts DC.
If a battery has 100 amp hours at 12 volts dc how many amp hours will it have with a 120 volt ac inverter connected?
The amp hours capacity of a battery remains the same whether it is connected to a 12-volt DC load or a 120-volt AC inverter. So, the battery would still have 100 amp hours regardless of the inverter voltage.
Why are the outputs of AC generators multiples of 120 volts - like 120 volts and 240 volts and 480 volts?
It is simply a product of standardization.
What electric current is used in Mexico?
AC, 120 Volts.
Why does ac line voltage read 185 volts?
I checked with my other meter and get 120 volts!
How many amps is a 1000watt at 120 volts ac?
p=vi. 1000/120 = 8.333amps
Is 12 volts peak to peak the same as 12 volts ac?
No. 12 volts peak to peak would be 6 in the positive polarity and 6 negative polarity. Simply saying 12 volts AC would be 12 volts in each polarity or 24 volts peak to peak
What is the electric current in the US?
120 volts 60 Hz AC
What is the electrical current in the US?
120 volts 60 Hz AC
How do you reduce 12 volts to 3.7 volts?
If the voltage is AC a transformer can be used.
How long would a 12 volt 7 amp hour battery last if converted to 120 volts ac using 20 watts?
Assuming this could be done with no conversion loss a 20 watt load at 120 volts would require about 1/6 of an amp. A 7 ampere hour battery would run the load for 6 x 7 = 42 hours. However, if you actually built a circuit to up convert 12 volts DC to 120 volts AC there would be significant conversion losses.
