16. RESISTOR
Resist the flow of
current or flow of charge in a
circuit.

17. CAPACITOR
Capable of storing energy
in the form of electricity.

18. INDUCTOR
Stores energy in a
magnetic field when electric
current flows through it.

19. DIODE
Has two terminals that
are anode and cathode. It
allows electron current flow
from cathode to anode but it
blocks another direction.

20. TRANSISTOR
Used to control the flow
of current and voltage in the
circuits. Also used as detector
and amplifier.

21. INTEGRATED CIRCUIT
is a small chip that can
function as an amplifier,
oscillator, timer, microprocessor
or even computer memory. An IC
is usually made of silicon that can
hold anywhere from hundreds to
millions of transistors, resistors,
and capacitors.

22. LIGHT EMITTING DIODE
Emits light when current
flows through it.

23. FUSE
Safety device that
operated to provide
overcurrent protection.

24. SWITCH
“Make” or “break” an
electrical circuit, interrupting
the current or diverting it.

25. ANTENNA
Transmits and receives
radio waves.

26. EARTH GROUND
Used for zero potential reference
and electrical shock protection.

27. MULTIMETER
Also known as
a VOM (volt-ohm-
milliammeter). Use
to measure voltage,
current and
resistance.

28. VOLTMETER
Measures voltage. Has very high resistance. Connected
in parallel.
OHMMETER
Measures resistance.
AMMETER
Measures electric current. Has near zero resistance.
Connected serially.
