What is the difference between inductor and inductance?
Inductors can be used for a great many purposes. Terms, such as 'choke', 'reactor', etc., describe applications of inductors.
Why aren't inductors used in timer circuits?
Mostly because large value capacitors are less expensive and smaller than large value inductors.
What is the total inductance of a circuit containing three 5 mh inductors connected in a series?
Inductors in series add up, so 15 mH
Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
What is the equipment required to do a CT polarity test?
You shouldn't need to perform a polarity test on a CT, as its terminals are normally identified with polarity markings.
Different types of inductors?
There are a variety of types of inductors. These include coupled inductors, multi-layer inductors, ceramic core inductors, as well as molded inductors.
How are inductors classified?
Inductors are classified by its core type.
Why are inductors connected in series?
Inductors are connected in series in order to increase the inductance in the circuit.
Are capacitors and inductors active elements?
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
Do inductors conduct heat?
conductors conduct heat and electricity, and insulators keep the heat in. inductors give away energy as heat.
What are two examples of polarity?
-- negative polarity -- positive polarity
What is the difference between inductor and inductance?
Inductors can be used for a great many purposes. Terms, such as 'choke', 'reactor', etc., describe applications of inductors.
Why inductors are not used in active filters?
inductors are more expensive and complex.and they take up space. Their effect can be replicated by active circuits.
How does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Is unequal sharing of electrons acidic basic or polarity?
Polarity
Why are inductors not usually connected to an operational amplifier?
no
Why aren't inductors used in timer circuits?
Mostly because large value capacitors are less expensive and smaller than large value inductors.
