We could answer the question through the help of Faraday's
Law of Induction:
Volts induced = - N•dΦ/dt
where N is the number of turns, and
Φ is the magnitude of the magnetic field.
V = IR, or R = V / I
V = -18 * [13Wb – 4.5Wb] / 0.072s
V = -2125 volts the sign just specifies direction
R = -2125V / 190
A
R = -11.1842105 Ω
According to the research, the correct option is true. Applying an electric current to the x-ray tube causes electrons to be boiled off the filament, producing x-rays.
<h3>What is the x-ray tube?</h3>
This is the part of the equipment that generates the X-rays, which consists of the electrons being accelerated to energies of 30 to 150 keV and hitting a tungsten target producing X-rays.
Specifically, it contains the cathode and the anode, which is covered by a protective and insulating casing, where the electrons emitted by a filament in the cathode reach the anode strongly accelerated, generating X-ray emission as a consequence, being the basis of all devices using ionizing radiation.
Therefore, we can conclude that according to the research, the correct option is true. Applying an electric current to the x-ray tube causes electrons to be boiled off the filament, producing x-rays.
