Q

What is the DC plate voltage of a resistance-coupled amplifier state with a plate-supply voltage of 260 V, a plate current of 1 mA, and a plate load resistance of 100,000 ohms?

🔍 Key Concepts

• Ohm's Law: V = I × R • How voltage drops across a resistor in series with a supply • Relationship between plate supply voltage, voltage drop, and plate voltage

💭 Think About

• First, calculate the voltage drop across the plate load resistance using the given current and resistance. • Then, relate that voltage drop to the plate-supply voltage: is the plate at the full supply voltage, or is some voltage lost across the resistor? • Determine whether the plate voltage should be higher or lower than the supply voltage after the drop across the resistor.

✅ Before You Answer

• Convert current from milliamps (mA) to amps (A) before using V = I × R. • Be sure you are subtracting the correct quantity from the correct voltage (supply vs. plate). • After calculating, compare your result with the answer choices and check if it is physically reasonable (e.g., plate voltage cannot be higher than the supply in this simple series circuit).
