Question: What is the potential difference across a capacitor if it stores 20 µC of charge and has a capacitance of 5 µF?

Options:

Correct Answer: 4 V

Solution:

Using the formula V = Q/C, V = 20 µC / 5 µF = 4 V.

What is the potential difference across a capacitor if it stores 20 µC of charge and has a capacitance of 5 µF?

Step 1: Identify the charge stored in the capacitor, which is given as 20 µC (microcoulombs).
Step 2: Identify the capacitance of the capacitor, which is given as 5 µF (microfarads).
Step 3: Use the formula for potential difference (V) across a capacitor, which is V = Q / C.
Step 4: Substitute the values into the formula: V = 20 µC / 5 µF.
Step 5: Calculate the result: 20 µC divided by 5 µF equals 4 V.
Step 6: Conclude that the potential difference across the capacitor is 4 V.
