Question: What is the potential difference across a capacitor of 10 µF when it stores a charge of 20 µC?
Options:
2 V
0.5 V
1 V
3 V
Correct Answer: 2 V
Solution:
Using the formula Q = C * V, V = Q / C = 20 x 10^-6 C / 10 x 10^-6 F = 2 V.

What is the potential difference across a capacitor of 10 µF when it stores a charge of 20 µC?
Step 1: Identify the values given in the question. We have a capacitor with a capacitance (C) of 10 microfarads (µF) and a charge (Q) of 20 microcoulombs (µC).
Step 2: Convert the units to standard form. 10 µF is equal to 10 x 10^-6 F and 20 µC is equal to 20 x 10^-6 C.
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 x 10^-6 C) / (10 x 10^-6 F).
Step 5: Simplify the equation: V = 20 / 10 = 2 volts.
Step 6: Conclude that the potential difference across the capacitor is 2 V.
