A spark is formed when the electric field strength exceeds the dielectric field strength of air. Meaning that when an area of space's electronic strength exceeds the area surrounding it, a spark occurs to modulate or evenly distribute the electrical strength.
An Arc occurs when an highly conductive object with a high electrical charge is in the proximity of a highly conductive object with a low electrical charge, allowing the electrical field to travel through an area with lower conductive properties (such as air) to the object which is highly conductive but contains a lower charge than the other object. Rubbing your feet on a carpet and touching someone is a good example of this occurrence.
The difference in a spark and an arc is a spark is a singular occurrence which only needs a single particle to occur and in order to create or induce an Arc, two object are needed.
What else can I help you with?
Should their be a spark inside a light switch when it's turned on?
If you are seeing a spark then the switch should be changed out right away. The spark is created by bad contacts within the switch its self. These bad contacts will create heat and eventually destroy the switch. Make sure that the rating of the switch is greater than the load that is connected to it. The only time a switch might draw an arc is when it is opened but it should never arc when closing. Yes there should be a spark when a switch is put on.
How many square yards are in one arc?
None.A square yard is a measure of area in 2-dimensional space whereas an arc is a curved line segment. There can be no conversion between the two.
What controls the maximum gap the electrons can jump to form the arc?
The distance between the electrode and work and the type of atmosphere surrounding the arc. Voltage pushes the current across the gap and the longer the arc length the higher the voltage has to be. In the TIG (GTAW) process Helium is lighter than Argon which allows less resistance to the arc allowing it to jump greater distances. Both have limitations as to how far the arc will travel across a gap.
How many longitude lines are there between each meridian line?
"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
What is the length of arc in circuit breaker?
There are different arc lengths for different types and size breakers. The length of the arc is governed by the physical distance of the contact openings and the efficiency of the arc chutes to extinguish the arc.
What is the basic difference between electric spark and electric arc?
the time it duration for the action and voltage drop
What is the difference between the center of an arc and the midpoint of an arc?
there is not much difference
What is the difference between Arc tan and arc tan?
There is no difference in meaning between the two. It is usually spelled in lowercase, though (arc tan, or arctan).
What is difference between arc and Arc?
Nothing it just has a capital letter

Is there a difference between the arc of a chord and the arc of an angle?
the world may never know :D
What does a spark plug do?
A electrical charge from the coil goes through the spark plug wire to the plug were the plug turns it into a arc between the two contacts on the bottom of the plug. that arc ignites the fuel in the cylinder.
What is the difference between the measure of an arc and arc length?
They are normally the same. However, the measure of the arc could refer to the angle subtended at the centre of the radius of curvature.
What is the difference between oil and an air circuit breaker. please could you answer with detail as i am confused?
Arc developed during closing/opening operation is extinguished by air in ACB and by oil in OCB
What is the difference between arc and arch?
both are derived from latin word arcus means bow arch is a structure in the shape of arc arc is the imaginary shape you can draw
What is electrical arc?
Electrical arc is the discharge of charges in the air-gap between two electrodes. When the electrodes are excited the air between the electrodes get ionized and star conducting which causes cotinuous spark between them called arc.
What color of spark is at the end of a spark plug?
You will see a white spark because a spark plug produces an electrical arc
