Answer:
Power of the electron beam in the x-ray tube is 2304 W
Explanation:
Given;
voltage of the electron beam in the x-ray tube, V = 144 kV = 144 x 10³ V
current of the electron beam in the x-ray tube, I = 16.0 mA = 16 x 10⁻³ A
Power is given as the product of voltage and current in a circuit.
Power of the electron beam in the x-ray tube, P = V x I
Power of the electron beam in the x-ray tube, P = 144 x 10³ V x 16 x 10⁻³ A
P = 2304 W
Therefore, power of the electron beam in the x-ray tube is 2304 W
