Jacob’s Ladder- are called two electrodes arranged as in the figure. It most likely is the most beautiful application of an electric arc:)))
And it works like this: in the lower part of electrodes, an arc occurs, the air near it heats up and rises , the arc also rises and extinguishes, then the process repeats. The distance between the electrodes at the bottom should correspond to the maximum arc generation distance, and between the electrodes at the top is the maximum arc retention distance. The current must be at least 5 mA. For its supply, we will use the converter on the line.
These currents and voltages are deadly! You can easily hurt yourself. You build this electrical circuit at your own risk. Attention - fire hazard!
Here are the basic safety rules:
1. Use only one hand (place your other hand on your lap or in your pocket),
2. Boots must have an insulated sole,
3.Use a wooden stick or insulated pliers, touching or driving an electrical circuit,
4. By soldering, disconnect the chain.
5. Carefully read thesafety technique!
Safety measures when working with electricity
Rules for working with electrical appliances and wiring :
1. Always treat electricity with respect. Be alert, attentive, and when working with electrical devices and wiring, consider each action.
2. Check if the place of work is well lit enough to see what you are doing. Often during repairs to illuminate the workplace, you have to use a flashlight with a battery.
3. Never touch a few bare wires with your bare hand, even if you are sure that the circuit is disconnected. It may happen that by mistake the circuit is left on or turned on. Use the voltage tester and make sure that there is no voltage.
4. Arrange the exposed wires so that one cannot touch the other even by accident.
5.When making twists, connect the wires and isolate the twist. Only then proceed to the next connection.
6. Never interfere with live wiring. Always turn off the electricity before opening the appliance or electrical armature.
7. Do not rely on insulated tool handles or insulating gloves as a protective tool against electric shock. They protect, but only in case of accidental contact with bare wire under voltage.
8. Avoid working with electrical wiring and devices in wet places. If the place is damp, place a dry board under your feet and stand on it. Wear additional rubber-soled shoes for extra protection.
When replacing the light fittings, turn off the lights and carefully lower the light fixture. Remove the end caps from the twist and touch the plugs to the bare ends of the black and white wires. If the lamp lights up, the wires are energized. Check the switches and sockets in the same way.
9. Before completing the repair, review your actions to make sure that you didn’t forget anything.
10.Always insulate the ends with certified elements for connecting wires or insulating tape.
Never use stationery tapes or any other substitute.
Generally, in electricity there is a current that kills.If the flows are low there is a little danger.
