Quiz „Electrical“
1. A capacitor with a capacitance of 100 μF is currently charged to a voltage of 199.8V. How much additional energy is needed to charge it to a voltage of 301.4V. Give answer to 4 significant figures in Joules
W = 0.5 * C * U^2
∆W = W_end – W_start = 0.5 * C ((U_end)^2 – (U_start)^2)
2. How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.
Q = I * t
3. Which of the following statements is false regarding the difference between Lead-based batteries, Nickel-based batteries and Lithium-based batteries?
no solution currently
4. Three inductors are connected as shown in the following figure:
Given that L1 = 2L2, find L1 and L2 such that the equivalence inductance is L = 0.7 H. Give your answers in Henry, rounded to three decimal places separated by a comma (L1, L2)
5. The following processes have to be measured by the AMS. (Multiple choice)
See FSG rules 2023: EV5.8.1, EV5.8.1 & EV5.8.3, EV5.8.10
6. The previous season you could recuperate only 27% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 69% of the initially stored energy. Knowing that you had 6.3 kWh of energy in your accumulator during the last season, how much energy must your new accumulator have, if you assume, that it’s the same length and speed? Give answer in kWh
E_new = E_old * (1+0.27)/(1+0.69)
7. Which of the following statements about LV battery packs with lithium based chemistry other than LiFePo4 is not true?
See FSG rules 2023 T11.7.7
8. For this Wheatstone Bridge based NTC temperature measurement circuit, which is the lowest voltage measurement (VAB) that is possible to obtain at 60ºC? (NTC B: 3435 +/-1%) Give answer in Volts rounded to two decimal points.
9. 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

1. A racing car rolls to a stop on a horizontal course with an initial speed of v. It decelerates only by friction with a rolling resistance of μF, which is supposed to be independent of the current velocity. What is the distance s the car needs to stop? v = 300 km/h, μF = 0.15, g = 9.81 m/s2. Give your answer in meters, rounded to four significant places.

3. You would like to drink a cup of very hot coffee with milk early in the morning, but you are in a hurry and have only 5 minutes until you have to leave for work. At which time after brewing should you add the cold milk to the coffee and stir in order to decrease the temperature of the mixture as much as possible: a) 0 minutes (immediately), b) 2 minutes, or c) 4 minutes? Suppose that the stirring can be done instantaneously and that you need the last one minute for drinking.
brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature 0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
Please enter only the letter of the corresponding answer
The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait. So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.

5. The Wet Skid Pad World Record was set at FSN2019 by TU Delft. They managed to set a time of 4.901 for the left circle and a time of 5.031 for the right circle.

Question: What negative pressure △pU (vacuum) exists in the pipe compared to the external pressure p₀?
Result in Pa, two decimal numbers seperated by a point (exp. 15.3). Do not put the Unit in the field below.

9. A lorry contains an engine with a power of 0.255 W. The lorry drives for 51 s. Calculate the energy transferred in Joules and round to one decimal places.

10. During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.
