An industrial electrostatic paint sprayer has a nozzle that charges liquid paint droplets negatively as they are sprayed.
Complete the sentence about the paint sprayer. Choose the correct word from the box:
negative∣neutral∣positive\text{negative} \quad | \quad \text{neutral} \quad | \quad \text{positive}negative∣neutral∣positive
As the negatively charged paint droplets approach the earthed metal target, the surface of the target gains a ______________ charge.
Which of the following describes the direction of the electric field pattern around a negatively charged paint droplet?
The potential difference between the sprayer nozzle and the earthed target is 160 000 V160\,000\text{ V}160000 V. During a short spray burst, there is a total charge flow of 0.000 025 C0.000\,025\text{ C}0.000025 C.
Calculate the energy transferred during this burst. Use the equation: energy transferred=charge flow×potential difference\text{energy transferred} = \text{charge flow} \times \text{potential difference}energy transferred=charge flow×potential difference
