Question

Electrons in an X-ray tube are accelerated through 1.00×10^2 kV and directed toward a target to produce X-rays. Calculate the power of the electron beam in this tube if it has a current of 15.0 mA.

a) 15.0 W
b) 1500 W
c) 0.00150 W
d) 1.50 W

Answer 1

To calculate the power of the electron beam, multiply the voltage by the current.

Step-by-step explanation:

The power of a beam of electrons can be calculated using the formula:

Power = Voltage x Current

Given that the voltage is 1.00 × 10^2 kV and the current is 15.0 mA (which can be converted to 0.015 A), we can substitute these values into the formula:

Power = 1.00 × 10^2 kV × 0.015 A

Calculating this expression will give us the power of the electron beam in watts.
