What is a Capasitor and a Resistor?

Question

and how do they work?

Answer 1

A capacitor and a resistor are electronic components which are used in producing electronic circuits.

A capacitor, in its simplest form, is merely two conductive sheets seperated by a non-conductive material. As current is applied to the cathode and anode, charge is collected and stored within the capacitor. This charge can remain for a duration after the current supplying charge is removed, though it will eventually bleed off either due to parasitic resistance within the circuit or as significant time passes.

A resistor is a component whose sole function is to supply a specific amount of resistance to the circuit. In it's most fundamental state, resistance is defined by Ohm's law, which states that resistance is found by dividing current into voltage (R= V/I).

Both are basic, yet crucial parts to any electronic circuit.

Answer 2

Good question ! A capacitor and resistor are electronic parts used in various electronic and electric circuits. In radio circuits capacitors are used to block the flow of direct current while allowing alternating and pulsating currents to pass.The capacitor consists of two conducting surfaces separated from each other by an insulating material such as air, oil,paper,glass, mica or ceramic. A resistor is an electronic part that offers restiance to electric current. Both of these parts are used in various electronic circuits such as radio,tv dvd players audio amplifiers. These parts are needed for these appliances to run properly because these appliances need various amounts within the circuits of the appliance to bring the final result. These parts within the appliances do their work with other parts such as coils ,inductors transistors and vacuumn tubes or whatever the appliance circuit requires. Within the appliance these circuits depend on direct current to function and the resistor and the capacitor convert the current coming from the wall socket outlets which run at specific ac(alternating current) and need to be converted within the appliance for the appliance to perform it's function. Check out Ohm's Law. :)

Answer 3

Resistor will resist the flow of electricity/electrons within a circuit depending on the size of the resistor measured in Ohms.
Capacitor measured in Farads, is used to block DC voltage and Frequencies in the Circuit to allow for tuning and Noise Filtering.

Answer 4

A capacitor is one of the building elements of an electrical circuit and is used to store electric charge for later use.
A resistor is also a building element of an electrical circuit and can be used for converting electrical energy into heat energy or simply for producing a pathway for electricity to flow from one poit to another.
