What is the performance like of an electric stove rated for 240V that is connected to a 208V supply?

Not good.
The heating elements expect 240 volts. Possible, alternate burners elements can be purchased. (Read contact manufacturer.) Otherwise a buck/boost transformer can increase the voltage to 240 volts and the stove will run fine.
Essentialy, 208 volts has 86 % of the energy of 240 volts.

Say the power consumption of my 12v devise is 80 mA or less and the instructions say use a 12v 300 mA power supply and I use a 12v 800mA OK or not?
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.
An electric bulb is rated 220v and 100wWhen it is operated on 110v the power consumed will be what?
25w
What is the BTU output of an electric heater rated at 14.2 kw?
That is 50,000 BTU per hour.
Adding a 240 volt 20amp electric heater in my crawl space Would like to use my 20 amp circuit for outside condenser Both would never be on at the same time Do they make a switch for this?
Yes, what you are looking for is a double pole double throw switch. The center lugs are connected to the incoming line. Then the top lugs could be connected to the electric heater and the bottom lugs connected to the condenser. The trouble lies in finding a switch with a rating of 20 amps. These types of switches are usually used with a stand-by generator and rated at 100A and greater. Think I remember seeing one at 60A once. You might want to think of using a DPDT relay rated at 30A with a 120 volt coil. With a switch to operate it the relay. Depends in what part of the country you live, long winters switch off for heater, long summers switch off for conderser.
Why do two lights connected to one switch get dim?
Because when two lights use the same battery, both lights need the same power to work, so the power has to split in half making the bulb's brightness dimmer. Ridiculous. If the lamps are connected in series, they will be dim because half the available voltage is dropped across each lamp. In parallel, they will both have full brightness.
Is electric cooker connected in series or parallel?
All residential loads are connected in parallel, so that they share the same supply voltage, which is necessary for them to develop their rated power outputs.
Why is that when an electric bulb stay just as its bright when connected to a parallel circuit?
To operate at its rated power, a lamp must be subject to its rated voltage (the supply voltage). As each branch of a parallel circuit is subject to the same voltage (the supply voltage), each lamp will operate at its rated power.
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
How can you operate a electric motor rated at 400V 3phase 50Hz on a 400V 3phase 60Hz system?
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
How can you operate a electric motor rated at 400V 3phase 50Hz on a 480V 3phase 60Hz system?
Which circuit arrangement will give you brighter bulbs If you have two 5-watt bulbs connected in series and then in parallel?
It depends on the voltage rating of each lamp, and the value of the supply voltage. It's important to understand that a lamp will only operate at its rated power (therefore at its full brightness) when subject to its rated voltage.So, let's assume each lamp is rated at, say, 24 V.If connected in parallel across a 24-V supply, then they will both operate of full brightness.If connected in series across the same 24-V supply, then each lamp will be subject to half its rated voltage, and will be very dim.On the other hand, if connected in series across a 48-V supply, then they will each be subject to 24 V, and will both operate at full brightness.
How could you find the purpose of a parallel circuit?
For an electrical load, such as a lamp, heater or motor, to operate at its rated power, it must be subject to its rated voltage which always corresponds to the supply voltage. For this to happen, individual loads must be connected in parallel with the supply and with each other. So all the electrical loads in your home, in your car, etc., are ALL connected in parallel.
What is the purpose of using transformer in electric bell circuit?
To supply the bell, because the latter has a rated voltage that's lower than the mains.
How is the brightness of the lightness of the lights related to whether you connect the bulbs in series or in parellel?
For a lamp to operate at its rated power, it must be subjected to its rated voltage. Provided this is the case, then it doesn't matter whether lamps are connected in series or in parallel. For example, ten identical lamps, each rated at 12 V, will operate normally if connected in series across a 120-V supply (this is because they will each be subjected to a voltage drop of 12 V). They will also function normally if they are connected in parallel across a 12-V supply.
An electric lamp is rated at 60W the current it draws from a 230 V supply is?
P=VI so I=P/V I= 60/230 I=0.261 A
Why should a fuse of defined rating not be replaced with one with larger rating?
The fuse is rated to protect the equipment, the supply, and you. Change the fuse for a higher rating and you compromise your safety and equipment and supply safety; increasing the risk of electric shock and of fire.
How is engine performance rated?
Engine performance can be rated by horsepower or torque rating, depending on how powerful the engine is. Larger engines for car and boats are rated in horsepower. Smaller engines (>1horsepower) can be rated in torque rating.
