    Hi All,

    I am new to the chat. I am not from the automotive industry, so I was wondering why the power outputs for ultracaps is given in kV rather than Farads. Anyone able to provide a simple answer to reduce my confusion?

    Lessee: Farads (coulombs per volt) measures charge capacity, kV (kiloVolts) measures electrical potential, and kW (kiloWatts) measures power (energy per unit time). Charge times electrical potential = energy. We have a mix of units here. What is it you want to know about these ultracaps?

    It's been a few years (20+ ha ha), but as I recall capacitors had both a farad and voltage ratings. The farad (or microfarad back in my days) was its capacity. The voltage was a limit where the capacitor stoped being a capacitor and became a burned up short.
