ElectricCircuits
Solids & Fluids
Heat & Thermodynamics
Electrostatics
Electric circuits, Current and Resistance
Current is a movement of charge
Voltage and Electric Field
capacitor and wire
Electric Field is contained within wires
A mechanical battery
A real battery
Ex:
Electric Field inside D-cell
Resistance
defined phenomenologically: \(R = V/I\), Ohm's Law
defined phenomenologically: \(J = \sigma E\), Ohm's Law
Ex:
electric socks
defined through material's properties: \(R = \rho L/A\)
Ex:
reshaping a wire
Ex:
current and wire diameter
a water analogy
Simple electric circuits
in series; Kirchhoff's voltage rule (KVR)
in parallel; Kirchhoff's current rule (KCR)
equivalent resistance
Energy/power in electric circuits
defined: \(P = VI=I^2R = V^2/R\),
