You are watching: In electrical work resistance is often represented by the
ResistorsA resistor represents a given amount of resistance in a circuit. Resistance is a measure up of exactly how the flow of electric current is protest or "resisted." the is defined by Ohm"s legislation which states the resistance equals the voltage separated by the current.
Resistance is measured in Ohms. The Ohm is often represented by the omega symbol: Ω.The symbol because that resistance is a zigzag heat as shown below. The letter "R" is provided in equations.
CapacitorsA capacitor to represent the lot of capacitance in a circuit. The capacitance is the capability of a ingredient to keep an electric charge. You have the right to think of it together the "capacity" to store a charge. The capacitance is identified by the equation
In a DC circuit, a capacitor becomes an open up circuit blocking any DC current from pass the capacitor. Just AC current will pass with a capacitor.Capacitance is measure up in Farads.The symbol because that capacitance is 2 parallel lines. Occasionally one that the currently is bent as shown below. The letter "C" is used in equations.
InductorsAn inductor to represent the quantity of inductance in a circuit. The inductance is the capability of a ingredient to create electromotive force as result of a readjust in the circulation of current. A straightforward inductor is made by looping a wire right into a coil. Inductors are offered in electronic circuits to mitigate or protest the readjust in electric current.In a DC circuit, one inductor looks like a wire. It has no affect when the current is constant. Inductance only has an result when the existing is transforming as in one AC circuit.Inductance is measured in Henrys.The symbol for inductance is a collection of coils as displayed below. The letter "L" is offered in equations.
Interesting Facts about Resistors, Capacitors, and InductorsThe resistance the a material is the opposite or the inverse of the conductivity.The Ohm is called after German physicist Georg Ohm.The Farad is called after English physicist Michael Faraday.The Henry is named after American scientist Joseph Henry.Combinations the capacitors, inductors, and resistors are used to construct passive filter that will only enable electronic signal of specific frequencies to happen through.
