AC Electrical Devices & schematics symblos
Electronic component are classed into either being Passive
devices or Active devices.
By using schematics symbols we can represent real-life devices.
 Resistance
-This is a resistance, measured in units ohms, . Most often it will be a
resistor.
 Inductor
- A schematics symbol inserted into an electrical circuit to introduce a
specified inductance.. Most often it will be a coil.
Inductance-
The property of a circuit which impedes a change in current. Inductors are the
usual source of inductance. Inductance is measured in henrys. In electronic
circuits, the usual measure of inductance is henrys (H), milihenrys (mH) or
microhenrys (�H), 1, 1e-3 or 1e-6 henrys respectively.
 or
 Capacitor
- A schematics symbol inserted into an electrical circuit to introduce a
specified capacitance.
Definition: The property of a circuit which impedes a change in voltage.
Capacitors are the usual source of capacitance. Capacitance is measured in
farads in honor of Michael Faraday. In electronic circuits, the usual measure of
capacitance is microfarads (�F) or picofarads (pF), 1e-6 or 1e-12 farads
respectively.
 This is
a AC voltage source, with a voltage of , measured in units of volts, V. The most
common AC Voltage Source you will see will be a home unit. .
 A device
inserted into an electrical circuit to introduce a specified alternating current
(AC). An AC current has a magnitude, phase and frequency.
