RL circuits In an RC circuit, while charging, Q = CV and the loop rule mean: charge increases from 0 to CE current decreases from E/R to 0 voltage across capacitor increases from 0 to E In an RL circuit, while charging, emf = Ldi/dt and the loop rule mean: magnetic field increases from 0 to B current increases from 0 to E/R voltage across inductor decreases from  E to 0
