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 2arrow_forward

If this number of electrons moves uniformly from the left end of the wire to the right end in 1 ms (millisecond), what is the current flows through the wire? iii. How many electrons must pass a given point in 1 minute to produce a current of 10 A? iv. If the charge profile across the cross section of the conductor from left to right is given by g(t) = t + 0.2est C for t2 0 and zero for t < 0, plot the profile of the current that flows across the boundary. In what direction would the current flow? v. Repeat part (iv) for the charge profile (in Coulomb) sketched in Figure Q1(b)(ii).arrow_forwardQuestion 3 a. Some materials exhibit the property of superconductivity under certain conditions. State what is meant by superconductivity and explain the required conditions for the material to become superconducting. b.
