Connecting Potential and Current
A light bulb is connected to a battery with 1-mm-diameter wires. The bulb is glowing.
a. Draw arrows at points 1, 2, and 3 to show the direction of the electric field at those points. (The points are inside the wire.)
b. Rank in order, from largest to smallest, the currents I1,I2, and I3 at points 1 to 3.
