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?

Voltage regulation measures how much the output voltage changes from no-load to full-load, expressed relative to the full-load voltage. It’s calculated as (V_no_load − V_full_load) / V_full_load × 100%. Here, the no-load voltage is 12 V and the full-load voltage is 10 V. The drop is 2 V. So, 2 / 10 × 100% = 20%. Thus, the percentage regulation is 20%. (Using the no-load voltage as the reference would give about 16.7%, but the standard definition uses the full-load voltage.)
