Question

9 multiple choice 1 point as the ma doubles, the number of electrons flowing from cathode to anode increases fourfold. increases twofold. decreases twofold. increases by 50 percent. 10 multiple choice 1 point the product of tube current and exposure time is equal to kvp. x - ray beam quality. x - ray beam quantity. the hvl.

Explanation:

For question 9, current (mA) is directly proportional to the number of electrons flowing. So when mA doubles, the number of electrons doubles. For question 10, the product of tube - current and exposure time is related to the number of x - rays produced, which is x - ray beam quantity.

Answer:

1. B. increases twofold
2. C. x - ray beam quantity
