WebSep 12, 2024 · Figure 14.6. 1: (a–d) The oscillation of charge storage with changing directions of current in an LC circuit. (e) The graphs show the distribution of charge and current between the capacitor and inductor. In Figure 14.6. 1 b, the capacitor is completely discharged and all the energy is stored in the magnetic field of the inductor. WebI = Δ Q / Δ t. I is the current in amps (A). ΔQ is the electric charge in coulombs (C), that flows at time duration of Δt. Δt is the time duration in seconds (s). Example. When 5 coulombs flow through a resistor for duration of 10 seconds, the current will be calculated by: I = Δ Q / Δ t = 5C / 10s = 0.5A.
