Circuit Models
Ideal Model Representations
Ideal voltage source
No matter how much current it provides, the voltage stays the same.
Ideal temperature difference
This is also called a thermal reservoir. No matter how much heat flow this "reservoir" provides, the temperature stays the same.
Ideal current source
No matter the voltage, the current stays the same.
Ideal heater
Creates the same amount of heat flow, no matter the temperature difference.
Correspondence between thermal and electrical
Heat flow (power) -- Electrical Current
Temperature difference -- Voltage difference
Ohms Law
Thermal Heat Flow
Think of $q$ as current. Think of $\Delta T$ as voltage. Think of $1/UA$ as resistance.
