1. Made from a variety of materials, such as carbon, this inhibits the flow of current.
RESISTOR
CAPACITOR
INDUCTOR
RELAY
2. This consists of two plates separated by a dielectric and can store a charge. Useful in tuning and filtering circuits, it blocks DC while passing AC.
RESISTOR
CAPACITOR
INDUCTOR
DIOD
3. This can consist of a simple wire wound into a helix. It developes a magnetic field when current passes through it. It is also used in tuning circuits and filters. This one passes DC and blocks AC.
RESISTOR
CAPACITOR
INDUCTOR
DIODE
5. This is a type of semiconductor that only allows current to flow in one direction. It is usually used to rectify AC signals (conversion to DC).
RESISTOR
CAPACITOR
INDUCTOR
DIODE
5. This consists of an electromagnet, which is used to open or close a contact(s). It is used in switching that requires isolation or high power.
RELAY
TRANSISTOR
TRANSFORMER
ZENER DIODE
6. This is a type of semiconductor in which the flow of current can be controlled through a base or gate terminal. It is usually used for electronic switching or amplifiers.
TRANSFORMER
TRANSISTOR
DIODE
RELAY
7. This consists of usually two coil windings which usually share a magnetic core. It is used to convert an AC source or signal into another AC source or signal with the same power (ideally) but different voltage and current.
CAPACITOR
DIODE
TRANSFORMER
TRANSISTOR
8. This is a special type of diode that breaks down when a critical reverse voltage is applied. It is most commonly used to regulate voltage.
TRANSFORMER
DIODE
RESISTOR
ZENER DIODE
9. This is a special type of diode that lights up when a small voltage is applied. They are usually used as indicators or in numerical or alphanumerical displays.
LED
LCD
LAD
PLASMA
10. This is a type of display that uses tiny polarized crystals that align when current is passed through them. Used in conjuction with a polarized lens they darken when energized. They are very popular in watches, calculators, and lap-tops.
PLASMA
LCD
LED
OLDE
If your computer monitor turns on but doesn’t seem to display an image (or even the built-in info screen), what is probably wrong?
Your computer monitor isn’t connected to your computer correctly.
The light bulb (or LED bulb) which provides the lighting for your monitor isn’t working correctly
The monitor firmware is broken.
You used the wrong device driver on your computer for your current monitor
What is the most likely cause of a Windows Error (Blue Screen of Death) on a typical home computer?
Bad computer memory (RAM) causes most Windows errors.
Damage to the operating system (Windows) from a computer virus causes most Windows errors.
Bugs in Microsoft Windows cause most Windows errors.
Bugs in non-Microsoft products cause most Windows errors.
What are two computer problems easily diagnosed just by listening to your computer?
You can hear sound card problems and video card problems.
You can hear memory problems and computer monitor problems.
You can hear magnetic hard drive problems and fan problems.
You can hear network card problems and CPU problems.
Can you replace a sound card or video card built into your motherboard (integrated sound and video)?
Yes, you can replace built-in components by using the right replacement modules.
Yes, you can replace built-in components using generic replacement modules.
Yes, you can replace built-in components, but you will need custom replacement parts
No, you can’t normally replace built-in components
Buy a new device to replace the one which doesn’t work.
Use a shorter cord.
Plug the device into the USB port upside down.
Run the device through a USB adapter to clean up the signal.
Power-On Self-Theck (POST) can warn you when a device will fail.
Redundant Array (of) Independent Disks (RAID) can warn you when a device will fail
Self-Monitoring and Reporting Technology (SMART) can warn you when a device will fail.
Microsoft Checkdisk can warn you when a device will fail.
What is usually the easiest way to fix an application that won’t start anymore?
Run your virus scanner to fix the application because you probably have a virus.
Reboot your computer to fix the application because it’s probably a system error.
Uninstall and reinstall the application to reset the application completely.
Run Windows Registry repair software to fix the application because it’s probably a registry error.
If you get strange errors on your computer and don’t have a virus, what should you check next?
You should check your firewall in case a hacker is trying to break into your computer.
You should check your BIOS in case you don’t have Plug and Play enabled.
You should check your computer memory (RAM) in case it’s starting to fail.
You should check your Windows Updates for any patches you need to install.
If your computer is running slow, what default Windows program will help you find which program is using all of your processing power (CPU) or memory?
You can use Task Manager to find the offending program.
You can use the Control Panel to find the offending program.
You can use Scandisk to find the offending program
You can use the Device Manager to find the offending program.
If it takes a long time to open files, how can you usually speed up Windows without buying anything?
You can increase the speed Windows opens files on a magnetic hard drive by defragmenting the drive with Windows Defrag.
Rebooting Windows will make files open more quickly.
Running Windows Scandisk or Checkdisk to check your disk drive for errors will speed up opening files.
urning off your firewall will speed up opening files.
