Practice # 7 Capacitance, Inductance and Impedance

The time constant of the circuit.

6.28 x 10^18 electrons.

They create a phase shift between the voltage and current.

One farad is one coulomb of charge stored with one volt across the plates of the capacitor.

The symbol represents a fixed capacitor.

Capacitance is the ability of a system to store charge per unit voltage.

The unit of inductance is the henry.

Impedance is the total opposition that a circuit offers to the flow of alternating current.

τ = R × C, where R is resistance and C is capacitance.

V = I × Z, where V is voltage, I is current, and Z is impedance.
