What voltage is used in magnetron?

What voltage is used in magnetron?

Operation of Magnetrons This supply can provide an AC or DC voltage, with typical voltages ranging from 2.5 V to 15 V, and currents ranging from a few A to 100 A and above. The filament voltage has to be applied some time before the cathode voltage so the filament has sufficient time to pre-heat.

Is magnetron a cross field device?

The magnetron is called a “crossed-field” device in the industry because both magnetic and electric fields are employed in its operation, and they are produced in perpendicular directions so that they cross.

How does a magnetron sustain its oscillation using cross field?

Unlike the tubes discussed so far, Magnetrons are the cross-field tubes in which the electric and magnetic fields cross, i.e. run perpendicular to each other. In TWT, it was observed that electrons when made to interact with RF, for a longer time, than in Klystron, resulted in higher efficiency.

How do you control back heating in a magnetron?

If the magnetic field is made larger than the critical field (B>Be), the electron experiences a greater rotational force and may return back to cathode quite faster. All such electrons may cause back heating of the cathode. This can be avoided by switching off the heater supply after commencement of oscillation.

What voltage is a toaster?

103-120 Volts
Toaster in the US can operate at 103-120 Volts producing anywhere from 500-1500 Watts of power.

How many volts does a kettle use?

In Canada and the US, 115 volts or standard domestic line voltage. In Europe and other places it is 220 Volts. If you were actually asking how many volts does a kettle consume in operation then it depends on the manufacturer. Generally they element is in the 90 to 110 volt range.

What is cross field effect?

Crossfield effect is a parasitic sensitivity to a magnetic field which is orthogonal to the sensing direction of the sensor. This effect is nonlinear and it is common to all magnetic sensors containing ferromagnetic material.

What is Hartree voltage?

The Hartree voltage UH is derived for a cylindrical magnetron in the relativistic limit with and without an axial current. This voltage corresponds to the breakdown voltage of the magnetron in the presence of a rotating perturbation field.

What is the secondary voltage of a microwave transformer?

A typical home microwave transformer has two secondary windings. One winding provides 3.1 to 3.2 volts, while the high voltage winding provides between 1800 – 2800 volts (average ~2200 volts). The low voltage output is used to light the filament in the microwave-generating vacuum tube (called a magnetron).

What current does a 1200w toaster draw from 120v line in AMP?

10 Amps
Problem: The current drawn by a 1200-W toaster connected to 120 V is 10 Amps.

Is a toaster AC or DC?

Some larger electrical devices, like TVs, take AC power from the outlet and convert it to DC power inside the device. Still, other devices like lamps or toasters use AC power directly.
