Spark discharge apparatus with high-voltage power supply
High-voltage source with spark gap: demonstration of air breakdown and power supply of external high-voltage experiments, five demonstrations.
The apparatus combines a high-voltage source and a discharger: a housing with a control panel, a discharge rod with an insulating handle on the holder and a protective cap. The discharge gap is adjustable from 5 to 35 mm, a knob controls the voltage. Continuous and single-discharge modes are available. The apparatus supports five demonstrations: spark discharge and electrical breakdown of air, accumulation of charge to the breakdown voltage, conditions for the occurrence of a spark, and also the use of the device as a high voltage source for external experiments - for example, ignition of a combustible mixture. Used in demonstrations on electrostatics in physics lessons.
- 1.Housing with control panel - 1 pc.
- 2.Discharge rod with insulating handle - 2 pcs.
- 3.Discharge rod holder - 2 pcs.
- 4.Protective cap - 1 pc.
- Spark discharge: electrical breakdown of air between electrodes
- Accumulation of static electric charge and achievement of breakdown voltage
- Continuous and short-term (single) spark discharge modes
- High voltage source for demonstration experiments: supplying high voltage through wires to external installations - for example, igniting a flammable mixture in an experiment with a gas explosion
- Adjusting the discharge gap (from 5 to 35 mm) and voltage using the adjustment knob: conditions for the occurrence of air spark breakdown
