Part A 
Which point, A or B, has a larger electric potential? (Figure 1)
A
B
Part B
What is the potential difterence between A and B? Assume that E=1200V/m. Express your answer with the appropriate units. 
ΔV = 70 V
The metal spheres n (Figure 1) aro charged to ± 300 V
Part A Select a plausible contour map of the potential, showing and labeling the
-300 V, -200 V , – 100V ,…, 300 V equipotential surfacers 
A 14-cm-long nichrome wire is connected across the terminals of a 1.5 V battery.
Part A
What is the electric field inside the wire?
Express your answer to two significant figures and include the appropriate units.
E = 11 (V ⁄ m)
Part B What is the current density inside the wire?
Express your answer to two significant figures and include the appropriate units.
J = 7.1 × 106 (A ⁄ m2)
Part C
What is the current in the wire is 1.2 A, what is the wire’s diameter?
Express your answer to two significant figures and include the appropriate units.
d = 5.34 × 10-4 mm
