P4b- Uses of electrostatics
Cards in this deck (9)
- 1name 3 uses of static electricityrestarting the heart- defibrillators; reducing smoke particles in chimneys- dust precipitators; spraying
- 2explain how defibrillators workpaddles charged+put in good electrical contact with patient's chest; defibrillator discharges into patient; charge passes through them to make the heart contract
- 3how do dust precipitators remove smoke particles from chimneys??dust passes through charged metal plates/grids; becomes charged; attracted to earthed plates; forms larger particles; falls back down chimney
- 4the metal plates in dust precipitators are at a high what??voltage
- 5diagram of electrostatic dust precipitators:
- 6this is a man with defibrillators:
- 7what happens when you touch an electrostatic generator??
- 8how does crop spraying work??paint gun negatively charged; paint particles negatively charged; repel+spread out; panel positively charged; paint attracted to panel
- 9what charge is the car panel after it has been sprayed??no charge/neutral
