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 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.
What is the connections between resistance and current?
Ohm's LawVolts = Current x Resistance.
Sparking between contacts can be reduced by inserting a?
Capacitor in parallel with contacts.
Is Sparking between contacts can be reduced by inserting a Resistance in the line?
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 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.

Why would a circuit breaker switch spark?
A circuit breaker switch could spark due to a buildup of heat or a high level of current flowing through it. This can lead to arcing between the contacts inside the breaker, resulting in sparking. Additionally, loose connections or damage to the breaker can also cause sparking.
What is the insulator between the contacts of a bell push switch when it is of?
The insulator between the contacts of a bell push switch when it is off is typically made of non-conductive material such as plastic or rubber to prevent the flow of electricity between the contacts. When the switch is pressed, the insulator is compressed or moved aside, allowing the contacts to connect and complete the circuit, allowing electricity to flow to the bell or buzzer.
Why are the contacts in an electrical extension cord further back then a normal wall outlet?
A good, solid, connection between the socket's female contacts and the plug's male contacts, with a maximum area of overlap is essential. So there should be no difference whatsoever between the physical location of an extension cord's contacts and those of a wall outlet.
What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
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 does the resistance vs length graph show in terms of the relationship between resistance and length?
The resistance vs length graph shows that there is a direct relationship between resistance and length. As the length of the material increases, the resistance also increases.
