9 / 10

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.

10 / 10

Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)

a. A device above the segments to prevent arc flashes

b. Every wire used inside of the TSAC

c. A dividing element between the main fuse, the AIRs and the rest of the TSAC

d. Spare TSAC

e. An LV energy storage with a lithium iron phosphate chemistry

f. Both layers of the fire wall including the material that bonds them together

An object is fired vertically upwards from the ground at time t = 0 s in still air at a speed of 8.0 m/s. On the way up, what is the height of the object above the ground when it has a speed of 2.0 m/s. At what time does it reach this height on the way down? Give both answers separated by a comma to one decimal place.

Possible solution:

use this formula to calculate the required height: „v^2 = u^2 + 2as“ -> 3.1m
use same formula again to calculate the maximum height the object reaches -> 3.3m
then use this formula to calculate the time the object takes to reach maximum: „v=u + at“ -> 0.8s
calculate the time taken for the object to fall from the maximum height to 3.1m (first answer): „s =2at^2“-> 0.2s
add together the two calculated times -> 1.0s
