🔍 Key Concepts

• Effect of filament (heater) voltage on tube life and reliability • How low filament voltage changes electron emission in a vacuum tube • How high filament voltage affects physical stress and burnout risk

💭 Think About

• For each option, ask: Is this a true and relevant reason for keeping filament voltage at the recommended value? • Consider what happens inside the tube when the filament is run below its rated voltage versus above its rated voltage. • Think about whether multiple listed effects can be simultaneously true, or if only one can be correct.

✅ Before You Answer

• Confirm whether low filament voltage reduces electron emission and can disturb normal circuit operation. • Confirm whether high filament voltage increases temperature and the chance of filament burnout. • Decide if maintaining recommended voltage is important for only one, some, or all of the listed reasons.
