A time exposure of a Jacob's ladder A demonstration of Jacob's ladder Jacob's ladder at work. A Jacob's ladder (more formally, a high voltage travelling arc) is a device for producing a continuous train of electric arcs that rise upwards. The device is named for the Jacob's Ladder leading to heaven as described in the Bible. Similarly to the ...
A Jacob's ladder on top of the switch will cause the arc to rise and eventually extinguish. One might also find small Jacob's ladders mounted on top of ceramic insulators of high-voltage pylons. These are sometimes called horn gaps. If a spark should ever manage to jump over the insulator and give rise to an arc, it will be extinguished.
Picture of the Jacob's Ladder in the original Luther Bibles (of 1534 and also 1545). Jacob's Ladder (Biblical Hebrew: סֻלָּם יַעֲקֹב , romanized: Sūllām Yaʿăqōḇ) is a ladder or staircase leading to Heaven that was featured in a dream the Biblical Patriarch Jacob had during his flight from his brother Esau in the Book of Genesis (chapter 28).

When the distance between the electrode and the object becomes too great to maintain, the filament will break and a new filament will reform between the electrode and the hand (see also Jacob's Ladder, which exhibits a similar behavior). An electric current is produced within any conductive object near the orb.
Arcing horns (sometimes arc-horns) are projecting conductors used to protect insulators or switch hardware on high voltage electric power transmission systems from damage during flashover. Overvoltages on transmission lines, due to atmospheric electricity , lightning strikes, or electrical faults, can cause arcs across insulators (flashovers ...
Jacob's Ladder is a Grade I listed staircase leading from Jamestown, Saint Helena, up the side of Ladder Hill to Ladder Hill Fort. The name is a reference to the biblical Jacob's Ladder, a ladder extending to heaven. [1] The ladder is all that remains of a cable railway that was built there in the early 1800s. [2]
We Are Climbing Jacob's Ladder is a spiritual. [1] As a folk song originating in a repressed culture, the song's origins are lost. Some academics believe it emerged as early as 1750, [ 3 ] and definitely no later than 1825, [ 4 ] and was composed by American slaves taken from the area now known as Liberia . [ 3 ]
