🔍 Key Concepts

• Function of A, B, and C batteries in older radio/communication equipment • Difference between filament/heater power, plate/screen (high-voltage) power, and grid bias • How each battery type supports a specific part of a vacuum tube circuit

💭 Think About

• Which part of a vacuum tube needs low-voltage power just to heat it up so it can emit electrons? • Which part requires a relatively high DC voltage to attract and control the flow of electrons? • Which part needs a small, steady negative voltage to control the tube without drawing significant current?

✅ Before You Answer

• Match A battery with the function related to heating/filament current • Match B battery with the function related to high-voltage plate and screen circuits • Match C battery with the function related to grid bias (a small controlling voltage with almost no current)
