What effect does a speaker wire's gauge have on speaker sound quality? -
ANSWER✅✅ Lower gauge wires are thicker with better sound quality.
What's the primary advantage of a quad-band cell phone over a dual-band cell
phone? - ANSWER✅✅ Coverage area. There are four frequency bands used
throughout the world and a quad-cell phone would be able to access any of them.
When working with electricity, you should assume that all electrical equipment is
alive unless you know for certain otherwise. This prevents: - ANSWER✅✅ Personal
injury. The greatest concern when dealing with electricity is personal welfare.
The heat effect of current is created: - ANSWER✅✅ When the current overcomes
resistance in the wire, creating heat. This heat effect occurs when current must
overcome the resistance of wire.
What special type of diode is commonly used to regulate voltage? - ANSWER✅✅
Zener diode, which is available in a variety of voltages.
, Electromotive force is another way of saying - ANSWER✅✅ Voltage. It is the
pressure of the current.
A primary advantage of using a Li-Ion battery instead o a NiMH battery in your cell-
phone is: - ANSWER✅✅ Li-Ion battries. Much more so than Nickel Metal Hydride
[NiMH] batteries.
Transistors contain at least three terminals called the: - ANSWER✅✅ Base, emitter,
and collector.
To control a light fixture from two different wall switches, you should use: -
ANSWER✅✅ Two three-way switches.
A transistor is also called a: - ANSWER✅✅ Crystal amplifier.
To decrease capacitance, capacitors: - ANSWER✅✅ Should be connected in series.
A resistor marked 2.5K ohms has the value of: - ANSWER✅✅ 2,500 ohms. K = one
kilo or 1,000.
Ohm's law states: - ANSWER✅✅ Voltage [V] = Current [I] x Resistance [R]
An electromagnetic-induction device usually has which of the following materials in
its core? - ANSWER✅✅ Iron. It's easily magnetized and demagnetized, so it works
well for this device.
How many diodes should you expect to find in a bridge rectifier? - ANSWER✅✅ A
bridge rectifier [aka full wave rectifier] contains 4 diodes. Rectifiers convert AC to DC
current by only allowing it to flow one way.
Another name for cycles per second is: - ANSWER✅✅ Hertz [Hz]. The number of
times AC changes direction in one second is known as frequency, which is measured
in Hz.
Newer cell phones contain a removable memory card, which is often called a: -
ANSWER✅✅ SIM stands for Subscriber Identity Module. The card contains
information such as your phone number, billing information, and address book. It
makes switching phones much easier.
When current flows through a wire, the following influences are present: -
ANSWER✅✅ Voltage [electric potential], ohms [resistance], and amperes [current]
are always present when current flows through a wire.
Millihenries are related to: - ANSWER✅✅ Inductors, which are rated in millihenries.
Radar can operate at frequencies as high as: - ANSWER✅✅ 100,000 Megahertz
[MHz]
