What is the Charge and Error in a Parallel Plate Capacitor?

In summary, parallel plate capacitance is the ability of two parallel plates to store electrical charge when a potential difference is applied between them. It is calculated using the formula C = εA/d and is affected by factors such as distance between plates, plate area, material between plates, and dielectric constant. The unit of measurement for parallel plate capacitance is Farads (F) and it is used in various practical applications in electronics and energy storage.

A capacitor with capacitance of C = 8.5±1 μF has a potential difference of V = 4.5±0.4 Volts. What are the charge on the capacitor and the error in this value, in μC?

To find charge I just use Q = C*V correct? And how do I calculate the error?

Thank you!

For s=ab
[tex]\frac{\delta s }{s}= \frac{\delta a}{a} + \frac{\delta b}{b}[/tex]

Where [itex]\delta s[/itex] is the error in s and similiarly for a and b.

Another way to say that is that for multiplying and dividing, the % errors in quantities are added.
