1.	Heat at the rate of 200 W is produced in an X-ray tube operating at 20 kV. Find the current in the circuit. Assume that only a small fraction of the kinetic energy of electron is converted into X-rays.
Answer» Correct Answer - 1 Heat produced //sec`= 200W` `implies I = (200)/(V) = (200)/(20 xx 10^(3)) = 10 mA`
