The Field Force and the Field Flux. Fields have two measures: a field force and a field flux.The field force is the amount of "push" that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage ("push") and current (flow) through a …

Learn MoreOnce fully charged, the capacitor blocks the flow of direct current, acting as an open circuit. They act like a temporary storage device and hold this charge indefinitely as long as the supply voltage is present. Thus a capacitors charging current can be defined as: i …
Learn MoreOnce the current is established, it is thus also a constant. Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses ...
Learn MoreWhen an initially uncharged ((q=0) at (t=0)) capacitor in series with a resistor is charged by a dc voltage source, the capacitor asymptotically approaches the maximum charge. As the charge on the capacitor increases, the current exponentially decreases from the initial current: (I_0=ε/R).
Learn MoreFigure 21.38 shows a simple RC circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor. As charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like ...
