10.S: Direct-Current Circuits (Summary)

An RC circuit is one that has both a resistor and a capacitor. The time constant τ τ for an RC circuit is τ = RC τ = R C. When an initially uncharged ( q = 0 q = 0 at t = 0 t = 0) capacitor in series with a resistor is charged by a dc voltage source, the capacitor asymptotically approaches the maximum charge.
