Final answer:
The x-ray transformer and the x-ray generator supply electrical power to the x-ray tube.
Step-by-step explanation:
The components that supply electrical power to the x-ray tube are the x-ray transformer and the x-ray generator.
- The x-ray transformer is responsible for increasing the voltage from the power source to the high voltage needed to accelerate the electrons in the tube.
- The x-ray generator produces the necessary electrical current for the x-ray tube to function and generate x-rays.
The kVp meter and mA meter are used to monitor the voltage and current respectively, but they do not supply electrical power to the x-ray tube.
