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.

What does the symbol stand for?

Made from a variety of materials, such as carbon, this inhibits the flow of current.

What does the symbol stand for?

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.

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).

This is a type of display that uses tiny polarized crystals that align when currentis passed through them. Used in conjuction with a polarized lens they darkenwhen energized. They are very popular in watches, calculators, and lap-tops.

If two resistors are placed in series, is the final resistance:

What does LED standfor?

If a small value of capacitance is connected in parallel with a large value, the combined capacitance will be:

What does the symbol stand for?

What does the symbol stand for?

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.
