Q

Given a power supply with a no load voltage of 12 volts and a full load voltage of 10 volts, what is the percentage of voltage regulation?

🔍 Key Concepts

• Voltage regulation definition for a power supply • Relationship between no-load voltage and full-load voltage • Basic percentage calculation using a formula

💭 Think About

• How does voltage typically change from no-load to full-load in a real power supply? • Which voltage (no-load or full-load) belongs in the denominator of the voltage regulation formula? • After you compute the raw fraction, what do you do to convert it into a percentage?

✅ Before You Answer

• Write the regulation formula in symbols before plugging in numbers, and be sure which voltage is V_no-load and which is V_full-load. • Double-check that you subtract in the correct order: higher voltage minus lower voltage, not the reverse. • After calculating the decimal value, multiply by 100 and compare to the answer choices to see which is closest.
