Wire loop in equilibrium conductor - all points at same potential Insert a battery no more equilibrium. Battery supplies energy to maintain a fixed potential difference between points A and B. Surface charge exists on the wires. Inside the conductor, the E field is directed along the wire. Charges move (F=qE) A B http://phet.colorado.edu/en/simulation/battery-voltage
dq i dt Steady state: Same current i in all parts of the loop i + Units: Ampere 1 A = 1C/s Current i http://phet.colorado.edu/en/simulation/conductivity

©University of Colorado, Boulder (2008) CT 29.10 Conservation of charge Current is flowing through wires which are part of a circuit, as shown. What is the current in the wire at the bottom right? 2 A I? 1 A A) 1 A to the left B) 1 A to the right C) 3 A to the left D) 3 A to the right E) none of these/not sure
Time between collisions is τ Drift speed v d typically about 1 m/hr 𝑖 = ?𝐴??
