No Load Voltage: 30 volts

Full Load Voltage: 25 volts

Full Load Current: 1 ampere




The output resistance of a DC power supply can be calculated using the following formula:

Output Resistance = (No Load Voltage - Full Load Voltage) / Full Load Current

Substituting the given values in the formula, we get:

Output Resistance = (30 volts - 25 volts) / 1 ampere = 5 ohms

Therefore, the output resistance of the DC power supply is 5 ohms.



Load regulation is the ability of a power supply to maintain a constant voltage output with varying load currents. It is expressed as a percentage of the output voltage change per unit load current change.

The load regulation of a DC power supply can be calculated using the following formula:

Load Regulation = ((No Load Voltage - Full Load Voltage) / Full Load Voltage) x 100%

Substituting the given values in the formula, we get:

Load Regulation = ((30 volts - 25 volts) / 25 volts) x 100% = 20%

Therefore, the load regulation of the DC power supply is 20%. This means that for every 1% change in load current, the output voltage will change by 0.2 volts.



The output resistance of a power supply represents the internal resistance of the power supply and is an important parameter in determining the voltage drop across the power supply under different load conditions. In this case, the output resistance of the DC power supply is 5 ohms, which means that the voltage drop across the power supply will be 5 volts at a full load current of 1 ampere.

Load regulation is an important parameter in determining the stability of a power supply under different load conditions. In this case, the load regulation of the DC power supply is 20%, which means that the power supply will maintain a constant output voltage within a range of +/- 20% of the full load voltage for varying load currents.
