b. A piece of pencil lead is connected in series with an ammeter and a power supply. The power supply is turned on. After a few minutes, although the potential difference across the pencil lead does not change, the current in the circuit increases significantly. Explain why the current increases. c. Electric fields are caused by both point charges and by parallel plates with a potential difference across them. Describe the difference between the electric field caused by a point charge and the electric field between parallel plates. Your answer should include a diagram of each type of field and reference to electric field strength. Question 2
What is the role of electron transfer in electrostatic charging by rubbing?
Each time constant of an exponential curve is equal to what percentage of the maximum amount of charge?
