Load regulation:

The capacity of a power supply to maintain a consistent output voltage despite changes in output current or load is known as load regulation. The power supply will give the appropriate and stable voltage to the circuit or system if the load regulation is good. The load regulation should ideally be zero indicating the output voltage of the supply is independent of the load and remains constant throughout.

The formula to find load regulation is,

Load regulation= $\frac{V_{n}-V_{f}}{100}$ * 100

$V_{n}$- No-load output voltage

$V_{f}$- Full load output voltage

Given

No-load voltage  -6V

Full load voltage -5.82V

Load regulation= $\frac{6-5.82}{5.82}$ *100

                         = $\frac{0.18}{5.82}$ *100

                         = 0.0309 *100

                         = 3.09%

The load regulation is 3.09%.
