CAPACITANCE
CAPACITANCE
Because of the effect of capacitance, an electrical circuit can store energy, even
after 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 in
voltage.
EO 1.8
Given a circuit containing capacitors, CALCULATE total capacitance
for series and parallel circuits.
EO 1.9
Given a circuit containing capacitors and resistors,
CALCULATE the time constant of the circuit.
Capacitor
Electrical 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 Figures
10b and 10c apply to all capacitors.
