What is the typical breakover voltage for a DIAC used in an electronic control circuit in which 120 VAC?
about ~30v
266 KW how many amps?
Watts = current x volts for a resistive load. You need to know a voltage to calculate amps. If it is a 120 VAC residential voltage it would be a whopping 266,000/120 = A or 2,216.7 Amps. If it is 240 VAC then half that. To put that in perspective the service to a typical residence might be between 100 and 200 Amps.
How many amps should a 0.5 horsepower motor draw?
Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.
How much current will a 120 VAC wall outlet pass through a connected 20 ohm circuit load?
The equation that you are looking for is I = E/R. Amps = 120/20 = 6 amps. This is one of the basic equations of Ohm's Law.
Can you replace a 250 Vac capacitor with a 370 Vac Capacitor?
Yes, generally, all other things being the same. By all other things I mean the capacitance, the type of capacitor for the application, etc.
What is the ratio of a 480vac single phase and a 120 vac secondary voltage?
The ratio for a 480 VAC to 120 VAC is 4 to 1.
What is the ac voltage reading between the bare copper wire and the hot black wire 120 vac or zero volt?
Should be about 120 VAC.
How do you build a 120 vac - 24 vdc power supply?
i dont no
A commonly-used device for stepping down 120 vac is?
Converter
What would the input current be for a 275 kva transformer with 2 phase of a 480 vac in and 120 vac at 20 amp output?

How 240 VAC achieved in a 120 VAC environment North America home?
By connecting two separate 120 VAC legs into one. If they are and if it comes to your home from a local utility they will be, it will add to 240. Whenever combining AC or Sine waves into one for the purpose of adding they must be in phase.
Is there anyway to get 120V 60Hz from a 220V 50Hz power supply?
You can purchase an inverter that accepts 220 VAC 50Hz input and produces 120 VAC 60Hz output. You can purchase an inverter that works from single phase or three phase electricity and can produce single phase or three phase output. You must specify the 120 VAC current load when choosing the inverter. You must also be sure the 220 VAC 50 Hz supply has sufficient current capacity to operate the inverter with the required 120 VAC current load. The inverter works by rectifying the 220 VAC 50 Hz input into DC energy. The inverter then uses switching solid state components to produce 120 VAC 60 Hz output from the DC energy.
How many watts is light bulb 120 VAC 60Hz 300mA?
Multiply the current by the voltage: 120 times 0.3, which is 40 watts.
Can you connect 2 wire to 3 wire house has black white red and ground Appliance has black white and ground?
It seems like you are describing the Red, Black, White and Ground in your electric panel. There is 240 VAC between Black and Red and 120 VAC between Black and White and 120 VAC between Red and White. The electric panel has two busses that supply 120 VAC on alternating breakers in your panel. Essentially, the Red turns into "black" in the panel for all practical purposes. If you have a 240 VAC circuit it essentially takes up to two vertical positions in your electric panel.

How can you find primary from secondary coil?
Primary and secondary are only terms of convenience based on the ratings and purpose of the transformer. If a transformer is labeled 120 to 240 volts, just pick a winding and apply 120 VAC. If the output is 240 volts you found the primary and secondary. If you apply 120 volts and get 60 volts out that means the side where you applied 120 VAC is the secondary.
