not it will be more effective to use a capacitor in parallel...
1/WC->0 as high frequency switching waves w-> inf.
C provides a shrt circuit path.

What is fault resistance?
Not all 'short circuits' are 'dead-shorts' -i.e. the resistance between the two conductors (or a conductor and earth) is not necessarily zero ohms -especially when the insulation between them has not completely broken down. The actual resistance is called the 'fault resistance'.
Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
What is inter base resistance in UJT?
The bulk resistance between the two bases, which will be different for different types of UJT. Consult the datasheet for the value.
What is resistance between primary and secondary winding of transformer?
The primary and secondary windings of a mutual transformer are electrically isolated, and should have 'infinite' resistance between them when measured appropriately (which depends on voltage ratings of the windings).
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.
Sparking between contacts can be reduced by inserting a resistance?
Capacitor in parallel with contacts.
Sparking between contacts can be reduced by inserting a?
Capacitor in parallel with contacts.
What does resistance spot weldin mean?
A spot welder has 2 copper contacts that compress two sheets of sheet metal. When current is applied to the contacts the steel in the sheetmetal acts as a resistor and causes enough heat to be formed that the two pieces melt together between the copper contacts.
Is there a difference between adult contacts and regular contacts?
There is no difference between adult contacts and regular contacts. There are two kinds of contact lenses; extended wear and disposable. There are also colored contact lenses.
What causes sparking in an electric buzzer?
The buzzer work with a magnetic coil that attractes the armature thus interrupting the current. This happens repeatedly to cause the buzz. When the current is interrupted the action of the coil produces a voltage that tries to maintain the current, and that causes a spark between the switch contacts.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
What material has resistance between a conductor and a insulator?
The resistance between a conductor and an insulator is: Wood, fabric, and water!
Comper between the theortical resistance and the partical resistance?
The theoretical resistance simply defines what resistance is while practical resistance refers to putting the theoretical resistance into action.
What is the relationship between air resistance and movement?
air resistance is cooler
What is the relationship between Power Ampere and resistance?
power=i square*resistance or power=v suare/resistance
What is the difference between on and off state resistance?
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
