two copper plates that are 50cm by 40m are sandwiched between 0.1mm
of a substance with a dielectric constant 7.5. what is the
capacitance of this capacitor?
Homework Answers
capacitance = (dielectric constant*ε0*Area) / (Distance between plates) = k*ε0A/D
= 7.5 * 8.845*10-12*(0.5*0.4)/(0.1*10-3) = 0.13281 µF Answer
