Capacitors come in values from picofarads (10-12 farads) to farads. They can be had in tolerances from .1% to 20%. For a list of standard values in 10% increments, go to http://www.ecelab.com/list-capacitors.htm
Inductors can be had from nh (nanohenrys) to henrys in tolerances from 1% to 20%. For standard values in 10% increments, go to http://www.rfcafe.com/references/electrical/inductor_values.htm

What is difference between impedance and reactance?
Impedance is the net reactance(for Capacitors and inductors in the circuit) / Resistance of the circcuit whereas reactance is the prperty of the individual passive components ( only capacitors n inductors) to resist the flow of charge.
What is the relationship between capacitors in series and resistors in series?
resistor isdefined as the opposing the current flow in a circuit. capacitor is defined as the store the electric field in one forth of the cycle and the another quarter cycle stored energy will be released
What is a De Sauty's bridge and give explanation about it?
De Sauty's bridge is an electric component that provides a method for making a comparison between two capacitors. It measures the values in terms of a standard capacitance.
Why are inductors connected in series?
Inductors are connected in series in order to increase the inductance in the circuit.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
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.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
Where is the store of electrical energy in a circuit?
Capacitors, inductors, and batteries all store electrical energy.
What is difference between impedance and reactance?
Impedance is the net reactance(for Capacitors and inductors in the circuit) / Resistance of the circcuit whereas reactance is the prperty of the individual passive components ( only capacitors n inductors) to resist the flow of charge.
How capacitors have made advancement in technology?
It is fair to say that without capacitors (and resistors and inductors) we would have no electronics. Better dielectrics are an area for improvement in capacitors, as is reduction in size.
Do magnets affect capacitors?
Yes, they do, but their affect is minimal. Magnets with their magnet fields affect inductors profoundly, but don't do to much to capacitors.
Why aren't inductors used in timer circuits?
Mostly because large value capacitors are less expensive and smaller than large value inductors.
How do you filter electricity?
One way is to use a pi filter composed of inductors and capacitors.
What is the relationship between capacitors in series and resistors in series?
resistor isdefined as the opposing the current flow in a circuit. capacitor is defined as the store the electric field in one forth of the cycle and the another quarter cycle stored energy will be released
How can electrical energy be stored?
Electric energy can be stored in batteries, inductors, and capacitors.
Why capacitors and inductors cannot be designed and used at higher frequency?
Capacitors and inductors can be designed and used at higher frequencies. It is just harder to do so, because one has to consider parasitic capacitance and inductance. As an example, at a high enough frequency, even a simple piece of wire is an inductor, and it has capacitance relative to itself and to other wires.
