1. The problem statement, all variables and given/known data The plates of a capacitor have an area of 0.4m2 and are separated by a distance of 0.5 micrometers. The material between the two plates is air with a dielectric constant of 1.0 One plate of the capacitor is given the charge of 4[tex]\muC[/tex]. The voltage across the capacitor is, in volts: 2. Relevant equations C=[tex]\epsilon[/tex](A/d) C=q/[tex]\Delta[/tex]V 3. The attempt at a solution So far I've been trying to calculate the capacitance with the first equation and then use the second equation for finding the change in voltage. I keep coming up with the wrong answer, though. Help please!
