💡 Hint

Common Mistakes

Using voltage or resistance instead of current as input.

The trace width calculation depends on the current flowing through the trace, so you need to provide the current value.

Complete the code to specify the copper thickness when calculating trace width.

PCB Design

trace_width = calculate_trace_width(current=5, copper_thickness=[1])

💡 Hint

Common Mistakes

Confusing copper thickness with voltage or current values.

Copper thickness is usually specified in ounces per square foot, such as 1 oz, which affects the trace width calculation.

hard

Fix the error in the code to correctly calculate trace width with temperature rise parameter.

PCB Design

trace_width = calculate_trace_width(current=3, temperature_rise=[1])

💡 Hint

Common Mistakes

Using strings with units or voltage values instead of numeric temperature rise.

The temperature rise should be a numeric value representing degrees Celsius, such as 10, not a string or voltage.

4fill in blank

hard

Fill both blanks to calculate trace width for a 2 oz copper thickness and 20°C temperature rise.

PCB Design

trace_width = calculate_trace_width(current=4, copper_thickness=[1], temperature_rise=[2])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing copper thickness and temperature rise values or using incorrect units.

Use '2 oz' for copper thickness and '20' for temperature rise in degrees Celsius to get the correct trace width.

hard

Fill all three blanks to calculate trace width with current 6A, copper thickness 1 oz, and temperature rise 15°C.

PCB Design

trace_width = calculate_trace_width(current=[1], copper_thickness=[2], temperature_rise=[3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Swapping current and temperature rise values or using incorrect copper thickness.

The current is 6 amps, copper thickness is 1 oz, and temperature rise is 15 degrees Celsius for the calculation.
