A static electricity generator has a metal dome that becomes positively charged.
Complete the sentence about the generator. Choose the correct word from the box:
negative∣neutral∣positive \text{negative} \quad | \quad \text{neutral} \quad | \quad \text{positive} negative∣neutral∣positiveWhen a student touches the positively charged metal dome, the student's hair gains a ______________ charge.
Which of the following describes the direction of the electric field pattern around the positively charged metal dome?
The potential difference between the metal dome and an earthed conductor is 250 000 V250\,000\text{ V}250000 V. When a spark jumps, there is a charge flow of 0.000 006 C0.000\,006\text{ C}0.000006 C.
Calculate the energy transferred by the spark. Use the equation:
energy transferred=charge flow×potential difference \text{energy transferred} = \text{charge flow} \times \text{potential difference} energy transferred=charge flow×potential difference8 exam-style questions on AQA GCSE Physics 2.5 Static electricity, covering 2.5.1 Static charge and 2.5.2 Electric fields.
