ELECTRICAL ENGINEERING CORRECTLY DEFINED TERMS.9
1. Capacitor - correct answer a passive two-terminal electrical component used to store
electrical energy temporarily in an electric field.
2. Diode - correct answer allows current to flow in one direction only.
3. Resistor - correct answer a passive two-terminal electrical component that implements
electrical resistance to reduce current flow, and, at the same time, act to lower voltage
levels within circuits.
4. Switch pole - correct answer poles on a switch define how many separate circuits the
switch can control
5. Switch throw - correct answer throw-count defines how many positions each of the
switch's poles can be connected to
6. Single pole single throw - correct answer a single-pole, single-throw (spst) switch is as
simple as it gets. It's got one output and one input. The switch will either be closed or
completely disconnected
7. Single pole double throw switch - correct answer spdts have three terminals: one common
pin and two pins which vie for connection to the common. Spdts are great for selecting
between two power sources, swapping inputs
8. Current - correct answer current is the rate at which electric charge flows past a point in a
circuit. In other words, current is the rate of flow of electric charge
9. Voltage - correct answer voltage, also called electromotive force, is the potential difference
in charge between two points in an electrical field
