An X-ray tube operating at 65kV has a tube current of 120mA. The tube produces X-ray with an efficiency of 0.8%

calculate the rate of heat production in the anode

rate = ?


I really dont get this question, anyone?

OK, one has voltage (65 kV) and current (120 mA), and voltage * current is power. Power is a rate of energy (production/transfer).

If X-rays are only 0.8% of the energy (0.008), then 0.992 of the energy/power goes into heating the anode.
