in order for electric potential to bridge a gap in an insulating substance, the potential first has to be high enough to ionize the substance. (in air this potential is around 1 million volts per meter) secondly, the energy has to have very few other paths around the gap, otherwise it will just take the less resistive path. once the substance ionizes enough, the electrons in the substance's atoms will go into a higher orbit and turn the atom into a conductor. with a dc current this causes an arc, not a spark. with ac the voltage hits 0, 60 times a second so the spark strikes repeatedly, unless the spark has enough current to stay "hot" through the zero-crossing (as it is called) this last effect is exploited in welding where the voltage is very low but an arc must still form.

Where does Dovey Coe take place?
It takes place in Indian Creek, NORTH Carolina
What is the definition of 6-cylinder engine?
The 6 cylinder means number of piston chambers inside the engine where the combustion takes place. That means, 6 pistons and spark plugs if its petrol. Greater the cylinders more the power, more the horse power and greater fuel consumption.
What is the difference between flow process and non flow process?
Flow process takes place in open system & non-flow process takes place in closed system.
Why energy conversion takes place in magnetic field?
electric
Do you have to grease your new spark plug wires?
You do not have to but it will be very good if you place a die-electric grease on points where ignition wires contact spark plugs and distributor/coil pack.
What energy takes place in electric cell?
Chemical energy is the form of energy that takes place in an electric cell. This energy is converted into electrical energy when the chemicals within the cell undergo chemical reactions, causing electrons to move from one terminal to another, thus generating an electric current.
How is fuel injection different from spark ignition?
Diesel fuel injection injects fuel into air that is hot enough to ignite the fuel. Spark ignition takes a fuel air mixture mixed and then drawn into the cylinder before ignition, then ignites with an electric spark.
What energy transformation takes place using appliances?
electric fan motor cycle washing machine electric stove television set
Is the 2014 Chevrolet Spark-EV electric or gas?
The 2014 Chevrolet Spark-EV is a electric fuel-powered vehicle.
Where you can find electric type Pokemon in Pokemon Crystal?

What energy transfers takes place when the turbine turn the generator?
kinetic energy is transfered to electric energy
What is an electric spark?
An electric spark is a form of electrostatic discharge that happens in the event that an electric field produces an ionized electrically conductive channel that results in emission of light and sound.
Can you turn water into steam with electric spark?
Absolutely. It's the HEAT of the spark that does it. Electric sparks are so hot they'll melt steel.
What role does the spark from the igniter play in the reaction that takes place when propane is burned in gas grill?
The spark provides enough energy to break the bonds of reacting molecules and get the reaction started.
How electronic gas lighter works?
Electronic gas lighters work off mains supply or battery packs and produce an electric spark which travels down a high tension wire to a sparker, situated next to the gas burner. When the burner is letting off gas and the spark reaches the sparker combustion takes place as long as there is adequate air.
