8. A thin circular, isolated wire made of copper with radius R lies on a table with its ends
connected to a Volt meter. Another, straight wire lies exactly along a diameter of the
circular wire, connected to an alternate current source i(t) = I0 sin(wt).
The experimental setup is shown in the following Figure:

Which effective voltage Ueff does the Volt meter display?
R = 10 cm, maximum current I0 = 1 A, f = 50 Hz.
Give your answer in Volts with three decimal places

The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.

e. The maximum temperature limit for LiFePo4 cells is 60°C

f. The TSAC can be protected from rear impact by a square tube with an edge length of and a wall thickness of 1.2 mm

g. There must be inspection holes in the side wall and the bottom of the TSAC if the wall thickness cannot be determined otherwise

h. All electrical safety items used for working on the accumulator must be rated for 1000 VDC

See FSG rules 2023. Correct answers:
