1

Create a list of common AC voltage levels

Create a list called ac_voltages with these exact values: 110, 220, 380, and 440 representing common AC voltage levels in volts.

Power Electronics

# Create the list ac_voltages with the specified voltage values
# Your code here

Need a hint?

Use square brackets to create a list and separate values with commas.

2

Add a variable for the desired output voltage

Create a variable called desired_voltage and set it to 220 to represent the output voltage level needed for a device.

Power Electronics

ac_voltages = [110, 220, 380, 440]
# Create the variable desired_voltage and set it to 220
# Your code here

Need a hint?

Use a simple assignment statement to create the variable.

3

Explain the main reasons for AC-AC conversion

Create a list called reasons_for_conversion with these exact string entries: 'Voltage adjustment', 'Frequency change', and 'Power quality improvement' to explain why AC-AC conversion is used.

Power Electronics

ac_voltages = [110, 220, 380, 440]
desired_voltage = 220
# Create the list reasons_for_conversion with the specified reasons
# Your code here

Need a hint?

Use a list of strings to store the reasons.

4

Summarize the benefits of AC-AC conversion

Create a string variable called summary with this exact text: 'AC-AC conversion allows devices to safely use the correct voltage and frequency, improves power quality, and increases energy efficiency.'

Power Electronics

ac_voltages = [110, 220, 380, 440]
desired_voltage = 220
reasons_for_conversion = ['Voltage adjustment', 'Frequency change', 'Power quality improvement']
# Create the summary string with the specified text
# Your code here

Need a hint?

Use a string assignment with the exact text inside single quotes.
