What is the difference between resistance and capacitance?
Resistance opposes current flow; capacitance stores charge.
Compare and contrast Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL).
KVL: Conservation of energy in a loop. KCL: Conservation of charge at a junction.
What is Electric Charge (q)?
A fundamental property of matter, measured in Coulombs (C). It can be positive or negative.
What is Resistance (R)?
How much a material opposes the flow of electric current, measured in ohms (Ω).
What is Resistivity (ρ)?
An inherent property of a material that determines its resistance, measured in ohm-meters (Ω⋅m). It depends on temperature.
What is Capacitance (C)?
A measure of a material's ability to store electric charge, measured in farads (F).
State Kirchhoff's Voltage Law (KVL).
The sum of the voltages around any closed loop in a circuit is zero.
State Kirchhoff's Current Law (KCL).
The total current flowing into a junction equals the total current flowing out of the junction.
What factors determine capacitor construction?
Distance between plates, surface area of plates, dielectric material between plates.
What is the formula for Resistance (R)?
R = \(\frac{\rho L}{A}\), where R = Resistance, ρ = Resistivity, L = Length, A = Cross-sectional area.
