Practice - 5 Tasks

1fill in blank

easy

Complete the code to identify the point where the current is maximum in a solar panel I-V curve.

Power Electronics

💡 Hint

Common Mistakes

Confusing Voc (open-circuit voltage) with maximum current.

Using zero as the maximum current value.

The short-circuit current (Isc) is the maximum current the solar panel can produce when voltage is zero.

2fill in blank

medium

Complete the code to find the voltage at which the solar panel produces zero current.

Power Electronics

if current == 0:
    voltage = [1]

💡 Hint

Common Mistakes

Using Isc instead of Voc.

Confusing voltage at maximum power point with zero current voltage.

The open-circuit voltage (Voc) is the voltage when the current output is zero.

3fill in blank

hard

Fix the error in the code to correctly calculate power from voltage and current.

Power Electronics

power = voltage [1] current

💡 Hint

Common Mistakes

Using addition instead of multiplication.

Using division or subtraction operators.

Power is calculated by multiplying voltage and current (P = V × I).

4fill in blank

hard

Fill both blanks to create a dictionary of voltage and current pairs where current is greater than zero.

Power Electronics

iv_points = {voltage: current for voltage, current in data.items() if current [1] 0 and voltage [2] 0}

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

A>

B<

C==

D!=

💡 Hint

Common Mistakes

Using equality or inequality operators incorrectly.

Using less than instead of greater than.

We want to include only points where both current and voltage are greater than zero.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that stores voltage, current, and power for points where power is positive.

Power Electronics

ivp_points = [1]: ([2], [3]) for [1], [2] in data.items() if ([1] * [2]) > 0

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

💡 Hint

Common Mistakes

Using incorrect variable names or mixing keys and values.

Not calculating power correctly in the condition.

The dictionary comprehension uses voltage as key, and a tuple of current and power as value, filtering points where power (voltage × current) is positive.
