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.

How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.

Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number

40% SoC -> 3.7V and 1.6 mΩ and 80% SoC -> 3.8V and 1.2 mΩ, total open-circuit voltage

71*3.7 + 71*3.8 = 532.5V

Total impedance = 71 * (1.6m/2) + 71*(1.2m/2) = 99.4mΩ

V*I = I^2*R * 80kW

I = 155 A

How long will it take to discharge C1 below 60V using the following constant current sink if it is initially charged at 565V? (MOSFET’s VGSth: 4V) Give answer to two decimal places in secs.

Circuit’s current: MOSFET will operate in linear zone, close to the activation voltage. Therefore, as VGSth is 4V, VS can be taken as 8V. From these 8V and the 47R current limiting resistor, the discharge current of the circuit will be 8/47->0,17A
As the constant current discharge of a capacitor depends on capacity, as V=i·t/C->
