AkHz voltage is applied to a 0.F capacitor, andmA of rms current is measured. What is the value of the voltage?
What is the capacitance when Q =C and V =V?
Five time constants are required for a capacitor to charge fully or discharge fully.
XC is inversely proportional to frequency and capacitance.
The ohm is the unit of capacitance.
Capacitance is directly proportional to plate area and plate separation.
Voltage leads current byin a capacitor.
The true power in a capacitor is zero.
A capacitor blocks ac but passes dc.
The dielectric constant is the ability of a material to establish an electric field.
