Question

For spot films utilizing cassettes, the mA setting is generally:

1. greater than 5 mA
2. less than 100 mA
3. greater than 100 mA
4. less than 5 mA

Answer 1

Option 3: The typical mA setting for spot films using cassettes is less than 100 mA, which accounts for the efficiency rate of electroplating-like processes.

Step-by-step explanation:

For spot films utilizing cassettes, the mA setting is typically less than 100 mA. Since the efficiency of processes like electroplating is much less than 100%, the actual current necessary for such applications may be greater than 0.1 A (or 100 mA). For a cassette recorder transformer converting 120 V to 12.0 V with a maximum current output of 200 mA, however, the values would differ as transformers are designed according to the appliance's power requirements.

For spot films utilizing cassettes, the mA setting is generally less than 5 mA. The mA setting refers to the milliampere setting, which determines the amount of current passing through an X-ray tube. Spot films are X-ray images taken with a small X-ray tube built into a cassette.
