Wish to write a code for an electronic load and a power supply for measuring Eff

[Hasan2025]

Hi there,
I am pretty new in python.
I need some help from your side.

Willing to run a program like this,

import pyvisa

# Initialize the resource manager and open the connection

rm = pyvisa.ResourceManager()
resource_address = "Your_VISA_Address"  # Replace with your actual VISA resource address
power_supply = rm.open_resource(resource_address)

try:
    # Identify the power supply
    print(power_supply.query("*IDN?"))

    # Set parameters (example values; replace as needed)
    voltage = 12.0  # Volts
    current = 5.0   # Amperes

    # Configure the power supply
    power_supply.write(f"VOLT {voltage}")
    power_supply.write(f"CURR {current}")

    # Enable the output
    power_supply.write("OUTP ON")

    # Measure output voltage and current
    measured_voltage = float(power_supply.query("MEAS:VOLT?"))
    measured_current = float(power_supply.query("MEAS:CURR?"))

    # Calculate power efficiency
    input_power = voltage * current  # Input power
    output_power = measured_voltage * measured_current  # Output power
    efficiency = (output_power / input_power) * 100

    print(f"Input Power: {input_power} W")
    print(f"Output Power: {output_power} W")
    print(f"Efficiency: {efficiency:.2f} %")

except Exception as e:
    print(f"An error occurred: {e}")

finally:
    # Turn off the output and close the connection
    power_supply.write("OUTP OFF")
    power_supply.close()

What is the question?
Does it work?
