How many electrons per second strike the target if the current is 0.500 mA?
. Electron guns are used in X-ray tubes. The electrons are accelerated through a relatively large voltage
and directed onto a metal target, producing X-rays.
(a) How many electrons per second strike the target if the current is 0.5 mA?
electrons per second
(b) What charge strikes the target in 0.8 s?
AQ=
C
X-Rays are just high energy light that can penetrate through flesh but not bones. The X-Ray machines use accelerated electrons hitting a target metal, such as copper or tungsten, generating X-Rays toward the patient. If the operator tells you that the target receives 0.8 A current, how many coulombs of charge is striking the target in 0.7 seconds?
