    "that" means "voltage".

    that of the capacitor = the voltage of the capacitor

    You need to know how capacitor works, then you can understand the sentence better, here is a link to explain how it works:


    Basically, capacitor is a device to store energy (in voltage form).

    The most common one is to use with an electrical motor. As you might know, to start a motor you need quite an amount of energy (especially, the voltage), therefore, lots of time, a motor will have a capacitor connects to it,

    and let the capacitor to build up the needed voltage before send the energy to the motor to turn (or start) it.
