How to find the maximum voltage that can be placed across a capacitor.

  • #1
How do you find the maximum voltage that can be placed across the capacitor?

It is a parallel plate strontium titanate filled capacitor, that has plates of area 0.78 m^2 and a separation of 0.070 mm. It also has a dielectric constant of 310 and a dielectric strength of 8.0 kV/mm.

I already figured out that the capacitance is 30.570 * 10^-6 F

But i can't seem to figure out how to find the max voltage.

The dielectric strength gives you the answer.Look at the units.What do they tell you?
