Task 31371.
The endless wire is bent as shown in the figure. As a conductor carrying a current I0 = 10 A. The point O is a small area of the conductive frame S. How to orient the frame, so that when you turn off the power at the maximum charge was framed? Find the maximum charge for the last frame, if r = 3 cm, S = 5 mm 2, and R = resistance beyond 0.05 ohms.
