The potential difference across a Coolidge tube is 20kV and 10mA...
The potential difference across a Coolidge tube is and current flows through the voltage supply. Only \text{0.5%} of the energy, carried by electrons striking the target, is converted into -ray. Then the power carried by -ray beam (in ) is
Correct answer
1
Step-by-step solution
Total power drawn by the tube
As \text{0.5%} of energy is carried by electrons, the power of X-ray will be~\text{0.5%} \times {P}_{T} = 1W
