DC CircuitsCAPACITANCECAPACITANCEBecause of the effect of capacitance, an electrical circuit can store energy, evenafter being de-energized.EO 1.5 DESCRIBE the construction of a capacitor.EO 1.6 DESCRIBE how a capacitor stores energy.EO 1.7 DESCRIBE how a capacitor opposes a change involtage.EO 1.8 Given a circuit containing capacitors, CALCULATE total capacitancefor series and parallel circuits.EO 1.9 Given a circuit containing capacitors and resistors,CALCULATE the time constant of the circuit.CapacitorElectrical devices that are constructed of two metal plates separated by an insulating material,called a dielectric, are known as capacitors (Figure 10a). Schematic symbols shown in Figures10b and 10c apply to all capacitors.Figure 10 Capacitor and SymbolsRev. 0 Page 9 ES-03
