What is 240v?
the voltage of the mains electricity in the UK
How many amps will an electric heater use if 440 volts are applied to it and the resistance is measured at 80ohms?
The formula you are looking for is I = E/R. Amps = Volts/Resistance.
Why 250 volts AC in New Zealand instead of 110 volts AC which America uses is one safer and is more energy footprint required to produce the higher voltage?
The reason for increasing the voltage in the electric network is, in fact, that it saves energy. The power dissipated in electric wiring is proportional to the square of the electric current. By increasing the voltage, the current decreases provided that the power consumption at the consumer is to remain constant. This means less loss in the electric network. For the same reason, very high voltages, hundreds of thousand volts, are used in long-distance wires. The voltage is converted using transformers when it reaches the consumers, with a relatively low power loss.
What frequency is used for electric power delivered to homes in Canada?
Homes in Canada use 240/120 volts at 60 cycles per second (60Hz) single phase. It is a split-phase system that delivers 240 volts to large domestic appliances (e.g. washing machines, dryers, air-conditioners, etc.) and 120 volts to lights and general socket outlets used for small appliances (coffee machines, electric shavers, televisions, etc.).
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
How do you increase a magnet?
Increase the electric volts
How do you increase a electro magnet?
Increase the electric volts
Is the strength of an electromagnet measured in volts?
That's a tricky question. Well, technically it is not measured in volts. The strength of an electromagnet depends on the electrical current which flows through its wires, but not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires. But when it comes to measuring the magnet, you have to refer to the magnetic field. Without it, there wouldn't be any "magnet." So, logically, to measure the strength of the magnet you must first measure the strength of the magnetic field. It's strength is measured in Volts per meter(V/m). So to measure the strength of the electromagnet you must measure the strength of the magnetic field whose formula is found in the next to last sentence. Hope this helps.
How many volts are found in infrared waves?
Basically, EM waves are not measured in volts. The intensity of the electric (and the magnetic) field would depend on the strength of the wave.
The strength of force is measured in?
Electric field strength is measured in Volts per meter, V/m OR equivalently, Newton per Coulomb, N/C.
What measures the flowing in a circuit?
The flow in a circuit is called the electric current and it is measured by voltages. The number of volts that are present in the charge will determine the strength of the electric current.
What is cheaper to run a electric fireplace on a 120 volts or 240 volts outlet?
Voltage does not affect the cost to run. You pay for the wattage, the higher the wattage the more it will cost to run.
How do Electric Vehicles Work?
By electric volts
What is the unit of dielectric strength?
In SI, the unit of dielectric strength is volts per meter (V/m). In U.S. customary units, dielectric strength is often specified in volts per mil.In physics, dielectric strength 2 meanings:Of an insulating material, the maximum electric field that a pure material can withstand under ideal conditions without breaking down.For a specific configuration of dielectric material and electrodes, the minimum applied electric field that results in breakdown.
How many volts do electric eels give out?
2 volts
How many volts are powering an electric train?
25,000 volts
How many volts it takes to run an electric car?
14 volts
