- *Effect of damage to sheet. A semiconducting sheet with metal painted electrodes is used in this experiment. The semiconducting material allows a very small current to flow between the electrodes, all over the sheet (2-D current - not just 1-D like in a wire). The potential difference between the electrodes is fixed by an external voltage source that is connected to each electrode. The electric field between the electrodes can be investigated with a test circuit. Any worn or damaged patches of the sheet act as an insulator and current cannot flow in this part. How will this effect the electric field between the electrodes compared to the case of no damage to the sheet? Select one: O a. The field is unchanged. O b. The field bends around the damaged part of the sheet. O c. The field is concentrated through the damaged part of the sheet. O d. The field is unchanged but the lines of equipotential stop at the damaged part of the sheet.RC Circuits 6.
