1. 01

   Electric flux and Gauss symmetry

   Electric flux is the oriented surface integral of E·dA. A negative flux reflects direction relative to the chosen normal, not negative area.

   Capacitors, RC transients and field energy

   For a linear capacitor Q=CV, with stored energy CV²/2. Potential difference and capacitance must refer to the same device.

   First law, ideal gases and entropy

   Use ΔU=Q−W, where W is work done by the system. A different sign convention is possible only when used consistently.
