What is the definition of Conductivity?
How well a material conducts electricity; the opposite of resistance.
What is the definition of Capacitance?
A capacitor's ability to store charge, measured in Farads (F).
What is the definition of Dielectric Constant (κ)?
How much a material can increase a capacitor's ability to store charge. Higher κ = more storage!
What is the definition of Electric Field?
The force field around a charged object that makes charges move.
What is the definition of Breakdown Voltage?
The voltage at which an insulator becomes a conductor.
What is the definition of Polarization?
How a dielectric's molecules align in an electric field.
What is the definition of Resistance?
Opposition to current flow, measured in Ohms (Ω).
What are the steps for a capacitor to store charge?
- Apply voltage. 2. Charge accumulates on plates. 3. Electric field forms between plates.
How does a dielectric increase capacitance?
- Polarization of molecules in the electric field. 2. Reduction of the electric field strength. 3. Increased charge storage capacity.
Label the components of a parallel plate capacitor diagram.
1: Positive Plate, 2: Negative Plate, 3: Dielectric (optional), 4: Electric Field Lines
