Q

Voltages used in CRT anode circuits are in what range of value?

🔍 Key Concepts

• Typical anode (final accelerating) voltage levels used in cathode-ray tubes (CRTs) for displays and radar scopes • Difference in magnitude between millivolts (mV), volts (V), and kilovolts (kV) • Why high accelerating voltage is needed to produce a visible trace on a CRT screen

💭 Think About

• Think about whether a very small voltage would be enough to accelerate electrons to strike the CRT screen with enough energy to produce visible light • Compare the order of magnitude of each option: which range best matches what you would expect for an electron beam device that needs strong acceleration? • Recall approximate high-voltage warning labels and insulation requirements you’ve seen on older radar sets or TV-type displays

✅ Before You Answer

• Convert in your mind between mV, V, and kV to see which answers are realistically high or low • Eliminate any ranges that are clearly too low to be considered high-voltage in electronic equipment • Consider which ranges would require special insulation and safety precautions typically associated with CRT anode circuits
