In Figure (a) below, a 10.44 V battery is connected to a resistive strip that consists of three sections with the same cross-sectional areas but different conductivities. Figure (b) gives the electric potential V(x) versus position x along the strip. The horizontal scale is set by x,- 10.24 mm. Section 3 has conductivity 3.010 x 10' (0-m)¹. What is the conductivity of section (a) 1 and (b) 2?

A square is 1 meter on each side. At each of the four corners there is one of each of the following charges: +1.0 × 10-8 C, -2.0 × 10¯8 C, +3.0 × 10-8 C, and + 2.0 × 10-8 C. What is the potential at the center of the square?

In Figure (a) below, a 9.09 V battery is connected to a resistive strip that consists of three sections with the same cross-sectional areas but different conductivities.
