What is the voltage rating when a string of A Christmas bulbs in series draws Ampere when connected to a volt source?
If the bulbs are wired in series, the voltage rating for each bulb is the source voltage divided by the number of bulbs in the series. You can tell if they're wired in series by removing a bulb. If all of the other lights go out, you have a series circuit. If all of the other bulbs stay lit, you have a parallel circuit. If half of the lights go out and the other half stay lit, you have two series circuits in parallel. The source voltage is about 110 volts in North America or about 220 volts in Europe (I don't know about Asia or Australia). If you have a series/ parallel mix, count only the bulbs that go out with the one you removed. For example, if you have 50 lights in one series in North America, the voltage across each bulb is about 2.2 volts.

Should Power sources connected in parallel have the same voltage rating?
yes
How many ampere in one hp?
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
What is mean KVA Rating of transformer?
copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN
What is the ampere rating of circuit A16?
14
What meaning circuit breaker 400af 300 at?
The "AF" stands for the Frame Ampere rating, so in this case will be 400 Amp Frame. The "AT" stands for Trip Ampere rating, and in this question will be 300 Amp Trip.
WHAT IS rectifiers 1N4007?
The 1N4007 is a diode with forward current rating of 1 ampere, and a reverse voltage rating of 1,000 volts.
What is 20 ampere hours in volts?
Ampere-hours is a battery hold-up time rating. Volts is a voltage rating. The two are not related, so the question cannot be answered as asked.
Do the outlet devices must have an ampere rating not less than the load to be served?
The receptacle must have a rating equal to or greater than the connected load.
What is the current carrying of an 1000kVA transformer?
You cannot answer this question without knowing the rated secondary voltage. Once you know this, divided the voltage into the volt ampere rating.
Should Power sources connected in parallel have the same voltage rating?
yes
What is ampere rating of an electrical kettle?
Divide its power rating by its voltage rating. These ratings are found on its nameplate. For example, a 3-kW kettle rated at 230 V will draw a current of approx. 13 A.
What is full load current rating for 1000kva xmer?
It depends on (1) its voltage rating, and (2) whether it is single phase or three phase. And the symbol for kilovolt ampere is kV.A -not 'kva'.
What is the different between using the low or high voltage in big three phase motors?
These types of motors are classified as dual voltage motors. The highest motor voltage rating is always double the lowest voltage rating. Dual voltage motors are more versatile in matching the system voltage supply that they are connected to. When the motor uses the highest voltage rating the coil legs are in series, dropping the high voltage across two coils. When the motor is connected to the low voltage rating the coils are connected in parallel dropping the low voltage rating across the two coils in parallel. As you can see no matter which configuration that you use the individual coils can never get a voltage across them greater than the lowest of the two voltages available. The connection diagram is usually on the underside of the motor's junction box lid.
How do you measure the volt ampere rating of a transformer?
Your transformer should have a namplate on it that states how many amps or fractions of amps it can produce. You would then multiply that number by your secondary voltage to get your VA rating. sec. voltage 12v X .05 amp = 12 X .05= .6va
Is using an adaptor that supply higher ampere rating than what is needed by the CCTV camera damage the device?
The camera will draw the amount of current it needs to function. As long as the voltage is within the rating of the camera you are okay.
