3) Consider the circuit shown, which has a 1.5 Volt cell driving a current through a narrower extent (“resistor”) of the same wire that the rest of the circuit is made of. Consider the corner indicated by the arrow. We have said many times that there are no charge accumulations inside a conductor in steady state, though there can be some on the surface. Also the current follows the direction of the E-field. a) What is the direction of the E-field just to the left of the indicated corner? (Draw an arrow on the figure to illustrate your answer.) b) What is the direction of the E-field just above the indicated corner? (Draw an arrow on the figure to illustrate your answer.) c) Explain as fully as possible what accounts for your answer to a), b). Equations accepted, but the answer can be entirely in words. 2 6 5 3 4 “Resistor"
